+ * different than those for the PNG-compared cases, and in the
+ * case of a failed renderMode comparison, how would we write the
+ * image to disk for examination?
+ *
+ * 2. Always compute image checksums from PNG format (either
+ * directly from the the bytes of a PNG file, or capturing the
+ * bytes we would have written to disk if we were writing the
+ * bitmap out as a PNG).
+ * PRO: I think this would allow us to never force opaque, and to
+ * the extent that alpha channel data can be preserved in a PNG
+ * file, we could observe it.
+ * CON: If we read a bitmap from disk, we need to take its checksum
+ * from the source PNG (we can't compute it from the bitmap we
+ * read out of the PNG, because we will have already premultiplied
+ * the alpha).
+ * CON: Seems wasteful to convert a bitmap to PNG format just to take
+ * its checksum. (Although we're wasting lots of effort already
+ * calling force_all_opaque().)
+ *
+ * 3. Make the alpha premultiply/unpremultiply routines 100% consistent,
+ * so we can transform images back and forth without fear of off-by-one
+ * errors.
+ * CON: Math is hard.
+ *
+ * 4. Perform a "close enough" comparison of bitmaps (+/- 1 bit in each
+ * channel), rather than demanding absolute equality.
+ * CON: Can't do this with checksums.

+ # Get ready for the ugly...
+ #
+ # - We have to nest our variables dictionaries multiple levels deep, so that
+ # this and other gyp files can rely on previously-set variable values in
+ # their 'variables': { 'conditions': [] } clauses.
+ #
+ # Example 1:
+ # Within this file, we use the value of variable 'skia_os' to set the
+ # value of variable 'os_posix', so 'skia_os' must be defined within a
+ # "more inner" (enclosed) scope than 'os_posix'.
+ #
+ # Example 2:
+ # http://src.chromium.org/viewvc/chrome/trunk/src/third_party/libjpeg/libjpeg.gyp?revision=102306 ,
+ # which we currently import into our build, uses the value of 'os_posix'
+ # within the 'conditions' list in its 'variables' dict.
+ # In order for that to work, it needs the value of 'os_posix' to have been
+ # set within a "more inner" (enclosed) scope than its own 'variables' dict.
+ #
+ # - On the other hand, key/value pairs of a given 'variable' dict are only
+ # inherited by:
+ # 1. directly enclosing 'variable' dicts, and
+ # 2. "sibling" 'variable' dicts (which, I guess, are combined into a single
+ # 'variable' dict during gyp processing)
+ # and NOT inherited by "uncles" (siblings of directly enclosing 'variable'
+ # dicts), so we have to re-define every variable at every enclosure level
+ # within our ridiculous matryoshka doll of 'variable' dicts. That's why
+ # we have variable definitions like this: 'skia_os%': '<(skia_os)',
+ #
+ # See http://src.chromium.org/viewvc/chrome/trunk/src/build/common.gypi?revision=127004 ,
+ # which deals with these same constraints in a similar manner.

+/** \class SkRRect
+
+ The SkRRect class represents a rounded rect with a potentially different
+ radii for each corner. It does not have a constructor so must be
+ initialized with one of the initialization functions (e.g., setEmpty,
+ setRectRadii, etc.)
+
+ This class is intended to roughly match CSS' border-*-*-radius capabilities.
+ This means:
+ If either of a corner's radii are 0 the corner will be square.
+ Negative radii are not allowed (they are clamped to zero).
+ If the corner curves overlap they will be proportionally reduced to fit.

+/** \class SkWeakRefCnt
+
+ SkWeakRefCnt is the base class for objects that may be shared by multiple
+ objects. When an existing strong owner wants to share a reference, it calls
+ ref(). When a strong owner wants to release its reference, it calls
+ unref(). When the shared object's strong reference count goes to zero as
+ the result of an unref() call, its (virtual) weak_dispose method is called.
+ It is an error for the destructor to be called explicitly (or via the
+ object going out of scope on the stack or calling delete) if
+ getRefCnt() > 1.
+
+ In addition to strong ownership, an owner may instead obtain a weak
+ reference by calling weak_ref(). A call to weak_ref() must be balanced my a
+ call to weak_unref(). To obtain a strong reference from a weak reference,
+ call try_ref(). If try_ref() returns true, the owner's pointer is now also
+ a strong reference on which unref() must be called. Note that this does not
+ affect the original weak reference, weak_unref() must still be called. When
+ the weak reference count goes to zero, the object is deleted. While the
+ weak reference count is positive and the strong reference count is zero the
+ object still exists, but will be in the disposed state. It is up to the
+ object to define what this means.
+
+ Note that a strong reference implicitly implies a weak reference. As a
+ result, it is allowable for the owner of a strong ref to call try_ref().
+ This will have the same effect as calling ref(), but may be more expensive.
+
+ Example:
+
+ SkWeakRefCnt myRef = strongRef.weak_ref();
+ ... // strongRef.unref() may or may not be called
+ if (myRef.try_ref()) {
+ ... // use myRef
+ myRef.unref();
+ } else {
+ // myRef is in the disposed state
+ }

- * The paint describes how pixels are colored when the context draws to
- * them. TODO: Make this a "real" class with getters and setters, default
- * values, and documentation.
+ * The paint describes how color and coverage are computed at each pixel by GrContext draw
+ * functions and the how color is blended with the destination pixel.
+ *
+ * The paint allows installation of custom color and coverage stages. New types of stages are
+ * created by subclassing GrEffect.
+ *
+ * The primitive color computation starts with the color specified by setColor(). This color is the
+ * input to the first color stage. Each color stage feeds its output to the next color stage. The
+ * final color stage's output color is input to the color filter specified by
+ * setXfermodeColorFilter which produces the final source color, S.
+ *
+ * Fractional pixel coverage follows a similar flow. The coverage is initially the value specified
+ * by setCoverage(). This is input to the first coverage stage. Coverage stages are chained
+ * together in the same manner as color stages. The output of the last stage is modulated by any
+ * fractional coverage produced by anti-aliasing. This last step produces the final coverage, C.
+ *
+ * setBlendFunc() specifies blending coefficients for S (described above) and D, the initial value
+ * of the destination pixel, labeled Bs and Bd respectively. The final value of the destination
+ * pixel is then D' = (1-C)*D + C*(Bd*D + Bs*S).
+ *
+ * Note that the coverage is applied after the blend. This is why they are computed as distinct
+ * values.

+/** \class SkAnimator
+
+ The SkAnimator class decodes an XML stream into a display list. The
+ display list can be drawn statically as a picture, or can drawn
+ different elements at different times to form a moving animation.
+
+ SkAnimator does not read the system time on its own; it relies on the
+ caller to pass the current time. The caller can pause, speed up, or
+ reverse the animation by varying the time passed in.
+
+ The XML describing the display list must conform to the schema
+ described by SkAnimateSchema.xsd.
+
+ The XML must contain an <event> element to draw. Usually, it contains
+ an <event kind="onload" /> block to add some drawing elements to the
+ display list when the document is first decoded.
+
+ Here's an "Hello World" XML sample:
+
+ <screenplay>
+ <event kind="onload" >
+ <text text="Hello World" y="20" />
+ </event>
+ </screenplay>
+
+ To read and draw this sample:
+
+ // choose one of these two
+ SkAnimator animator; // declare an animator instance on the stack
+ // SkAnimator* animator = new SkAnimator() // or one could instantiate the class
+
+ // choose one of these three
+ animator.decodeMemory(buffer, size); // to read from RAM
+ animator.decodeStream(stream); // to read from a user-defined stream (e.g., a zip file)
+ animator.decodeURI(filename); // to read from a web location, or from a local text file
+
+ // to draw to the current window:
+ SkCanvas canvas(getBitmap()); // create a canvas
+ animator.draw(canvas, &paint, 0); // draw the scene

+ We have two techniques for capturing the output of the supersampler:
+ - SUPERMASK, which records a large mask-bitmap
+ this is often faster for small, complex objects
+ - RLE, which records a rle-encoded scanline
+ this is often faster for large objects with big spans
+
+ These blitters use two coordinate systems:
+ - destination coordinates, scale equal to the output - often
+ abbreviated with 'i' or 'I' in variable names
+ - supersampled coordinates, scale equal to the output * SCALE
+
+ NEW_AA is a set of code-changes to try to make both paths produce identical
+ results. Its not quite there yet, though the remaining differences may be
+ in the subsequent blits, and not in the different masks/runs...
+
+ SK_USE_EXACT_COVERAGE makes coverage_to_partial_alpha() behave similarly to
+ coverage_to_exact_alpha(). Enabling it will requrie rebaselining about 1/3
+ of GMs for changes in the 3 least significant bits along the edges of

+// (16 - x)*(16 - y)*a00 + x*(16 - y)*a01 + (16 - x)*y*a10 + x*y*a11
+// to:
+// (16 - x)*a00 + 16*x*a01
+// much simpler. The simplification makes for an easy boost in performance.
+// - calculating 4 output pixels at a time.
+// This allows loading the coefficients x0 and x1 and shuffling them to the
+// optimum location only once per loop, instead of twice per loop.
+// This also allows us to store the four pixels with a single store.
+// - Use of 2 special SSSE3 instructions (comparatively to the SSE2 instruction
+// version):
+// _mm_shuffle_epi8 : this allows us to spread the coefficients x[0-3] loaded
+// in 32 bit values to 8 bit values repeated four times.
+// _mm_maddubs_epi16 : this allows us to perform multiplications and additions
+// in one swoop of 8bit values storing the results in 16 bit values. This
+// instruction is actually crucial for the speed of the implementation since
+// as one can see in the SSE2 implementation, all inputs have to be used as
+// 16 bits because the results are 16 bits. This basically allows us to process
+// twice as many pixel components per iteration.
+//
+// As a result, this method behaves faster than the traditional SSE2. The actual
+// boost varies greatly on the underlying architecture.

+/**
+ * An R-Tree implementation. In short, it is a balanced n-ary tree containing a hierarchy of
+ * bounding rectangles.
+ *
+ * Much like a B-Tree it maintains balance by enforcing minimum and maximum child counts, and
+ * splitting nodes when they become overfull. Unlike B-trees, however, we're using spatial data; so
+ * there isn't a canonical ordering to use when choosing insertion locations and splitting
+ * distributions. A variety of heuristics have been proposed for these problems; here, we're using
+ * something resembling an R*-tree, which attempts to minimize area and overlap during insertion,
+ * and aims to minimize a combination of margin, overlap, and area when splitting.
+ *
+ * One detail that is thus far unimplemented that may improve tree quality is attempting to remove
+ * and reinsert nodes when they become full, instead of immediately splitting (nodes that may have
+ * been placed well early on may hurt the tree later when more nodes have been added; removing
+ * and reinserting nodes generally helps reduce overlap and make a better tree). Deletion of nodes
+ * is also unimplemented.
+ *
+ * For more details see:
+ *
+ * Beckmann, N.; Kriegel, H. P.; Schneider, R.; Seeger, B. (1990). "The R*-tree:
+ * an efficient and robust access method for points and rectangles"
+ *
+ * It also supports bulk-loading from a batch of bounds and values; if you don't require the tree
+ * to be usable in its intermediate states while it is being constructed, this is significantly
+ * quicker than individual insertions and produces more consistent trees.

+/* Two-point radial gradients are specified by two circles, each with a center
+ point and radius. The gradient can be considered to be a series of
+ concentric circles, with the color interpolated from the start circle
+ (at t=0) to the end circle (at t=1).
+
+ For each point (x, y) in the span, we want to find the
+ interpolated circle that intersects that point. The center
+ of the desired circle (Cx, Cy) falls at some distance t
+ along the line segment between the start point (Sx, Sy) and
+ end point (Ex, Ey):
+
+ Cx = (1 - t) * Sx + t * Ex (0 <= t <= 1)
+ Cy = (1 - t) * Sy + t * Ey
+
+ The radius of the desired circle (r) is also a linear interpolation t
+ between the start and end radii (Sr and Er):
+
+ r = (1 - t) * Sr + t * Er
+
+ But
+
+ (x - Cx)^2 + (y - Cy)^2 = r^2
+
+ so
+
+ (x - ((1 - t) * Sx + t * Ex))^2
+ + (y - ((1 - t) * Sy + t * Ey))^2
+ = ((1 - t) * Sr + t * Er)^2
+
+ Solving for t yields
+
+ [(Sx - Ex)^2 + (Sy - Ey)^2 - (Er - Sr)^2)] * t^2
+ + [2 * (Sx - Ex)(x - Sx) + 2 * (Sy - Ey)(y - Sy) - 2 * (Er - Sr) * Sr] * t
+ + [(x - Sx)^2 + (y - Sy)^2 - Sr^2] = 0
+
+ To simplify, let Dx = Sx - Ex, Dy = Sy - Ey, Dr = Er - Sr, dx = x - Sx, dy = y - Sy
+
+ [Dx^2 + Dy^2 - Dr^2)] * t^2
+ + 2 * [Dx * dx + Dy * dy - Dr * Sr] * t
+ + [dx^2 + dy^2 - Sr^2] = 0
+
+ A quadratic in t. The two roots of the quadratic reflect the two
+ possible circles on which the point may fall. Solving for t yields
+ the gradient value to use.
+
+ If a<0, the start circle is entirely contained in the
+ end circle, and one of the roots will be <0 or >1 (off the line
+ segment). If a>0, the start circle falls at least partially
+ outside the end circle (or vice versa), and the gradient
+ defines a "tube" where a point may be on one circle (on the
+ inside of the tube) or the other (outside of the tube). We choose
+ one arbitrarily.
+
+ In order to keep the math to within the limits of fixed point,
+ we divide the entire quadratic by Dr^2, and replace
+ (x - Sx)/Dr with x' and (y - Sy)/Dr with y', giving
+
+ [Dx^2 / Dr^2 + Dy^2 / Dr^2 - 1)] * t^2
+ + 2 * [x' * Dx / Dr + y' * Dy / Dr - Sr / Dr] * t
+ + [x'^2 + y'^2 - Sr^2/Dr^2] = 0
+
+ (x' and y' are computed by appending the subtract and scale to the
+ fDstToIndex matrix in the constructor).
+
+ Since the 'A' component of the quadratic is independent of x' and y', it
+ is precomputed in the constructor. Since the 'B' component is linear in
+ x' and y', if x and y are linear in the span, 'B' can be computed
+ incrementally with a simple delta (db below). If it is not (e.g.,
+ a perspective projection), it must be computed in the loop.

- * Number of texture stages. Each stage takes as input a color and
- * 2D texture coordinates. The color input to the first enabled stage is the
- * per-vertex color or the constant color (setColor/setAlpha) if there are
- * no per-vertex colors. For subsequent stages the input color is the output
- * color from the previous enabled stage. The output color of each stage is
- * the input color modulated with the result of a texture lookup. Texture
- * lookups are specified by a texture a sampler (setSamplerState). Texture
- * coordinates for each stage come from the vertices based on a
- * GrVertexLayout bitfield. The output fragment color is the output color of
- * the last enabled stage. The presence or absence of texture coordinates
- * for each stage in the vertex layout indicates whether a stage is enabled
- * or not.
+ * Total number of effect stages. Each stage can host a GrEffect. A stage is enabled if it has a
+ * GrEffect. The effect produces an output color in the fragment shader. It's inputs are the
+ * output from the previous enabled stage and a position. The position is either derived from
+ * the interpolated vertex positions or explicit per-vertex coords, depending upon the
+ * GrVertexLayout used to draw.
+ *
+ * The stages are divided into two sets, color-computing and coverage-computing. The final color
+ * stage produces the final pixel color. The coverage-computing stages function exactly as the
+ * color-computing but the output of the final coverage stage is treated as a fractional pixel
+ * coverage rather than as input to the src/dst color blend step.
+ *
+ * The input color to the first enabled color-stage is either the constant color or interpolated
+ * per-vertex colors, depending upon GrVertexLayout. The input to the first coverage stage is
+ * either a constant coverage (usually full-coverage), interpolated per-vertex coverage, or
+ * edge-AA computed coverage. (This latter is going away as soon as it can be rewritten as a
+ * GrEffect).
+ *
+ * See the documentation of kCoverageDrawing_StateBit for information about disabling the
+ * the color / coverage distinction.
+ *
+ * Stages 0 through GrPaint::kTotalStages-1 are reserved for stages copied from the client's
+ * GrPaint. Stages GrPaint::kTotalStages through kNumStages-2 are earmarked for use by
+ * GrTextContext and GrPathRenderer-derived classes. kNumStages-1 is earmarked for clipping

+ * There are three types of "sources" of geometry (vertices and indices) for
+ * draw calls made on the target. When performing an indexed draw, the
+ * indices and vertices can use different source types. Once a source is
+ * specified it can be used for multiple draws. However, the time at which

+ * and pop methods. This allows the client to push the sources, draw
+ * something using alternate sources, and then pop to restore the original
+ * sources.
*
- * 1. Provide a cpu array (set*SourceToArray). This is useful when the
- * caller's client has already provided vertex data in a format
- * the time compatible with a GrVertexLayout. The array must contain the
- * data at set*SourceToArray is called. The source stays in effect for
- * drawIndexed & drawNonIndexed calls until set*SourceToArray is called
- * again or one of the other two paths is chosen.
+ * Aside from pushes and pops, a source remains valid until another source
+ * is set or resetVertexSource / resetIndexSource is called. Drawing from
+ * a reset source is an error.
+ *
+ * The three types of sources are:
+ *
+ * 1. A cpu array (set*SourceToArray). This is useful when the caller
+ * already provided vertex data in a format compatible with a
+ * GrVertexLayout. The data in the array is consumed at the time that
+ * set*SourceToArray is called and subsequent edits to the array will not
+ * be reflected in draws.
*
* 2. Reserve. This is most useful when the caller has data it must
* transform before drawing and is not long-lived. The caller requests
* that the draw target make room for some amount of vertex and/or index
* data. The target provides ptrs to hold the vertex and/or index data.
*
- * The data is writable up until the next drawIndexed, drawNonIndexed,
- * or pushGeometrySource At this point the data is frozen and the ptrs
- * are no longer valid.

+ * drawIndexedInstances, or pushGeometrySource. At this point the data is
+ * frozen and the ptrs are no longer valid.
+ *
+ * Where the space is allocated and how it is uploaded to the GPU is
+ * subclass-dependent.
*
* 3. Vertex and Index Buffers. This is most useful for geometry that will

- // Font matching:

-This is a nearly verbatim copy of the GLU tessellator source code from
-SGI's OpenGL Sample Implementation at
-http://oss.sgi.com/projects/ogl-sample/ . Per
-http://oss.sgi.com/projects/FreeB/ , the code is covered under the SGI
-Free Software License B, version 2.0, a copy of which is in
-LICENSE.txt in this directory.
-
-The following changes were made in order to incorporate this code:
-
- - The addition of a simplified gluos.h to eliminate operating system
- dependencies. The entry points to the tessellator were prefixed with
- Sk_ to avoid symbol collisions with any host OS version of GLU via
- #defines in gluos.h.
-
- - The removal of inclusion of GL/glu.h and replacement with an
- include of sk_glu.h.
-
- - In tess.c, the obsolete entry points gluBeginPolygon,
- gluNextContour and gluEndPolygon in tess.c were #if 0'd out.
- Default branches were added to the switch statements in GotoState.
-
- - In memalloc.h, the include of malloc.h was changed to an include
- of stdlib.h.
-
- - In normal.c, an unused variable "w" was removed from
- __gl_projectPolygon. #if guards were placed around the definition
- of the unused Normalize function.
-
- - In priorityq-heap.c, an #include of <limits.h> was added.
-
- - In sweep.c, IsWindingInside() was given a return value to silence a
- warning-as-error in release builds.
-
- - In sweep.c, DoneEdgeDict()'s fixedEdges was wrapped in #indef NDEBUG, to
- silence a warning-as-error in release builds.
-
- - In priorityq.c, render.c, and others: the construct "if(1)...else" was
- replaced with "do{...}while(1)" to silence a warning-as-error in Mac builds.
-
- - rename all __gl_ functions to Sk__gl_ to avoid conflicting with other
- static linkers of this library.

-General Polygon Tesselation
----------------------------
-
- This note describes a tesselator for polygons consisting of one or
- more closed contours. It is backward-compatible with the current
- OpenGL Utilities tesselator, and is intended to replace it. Here is
- a summary of the major differences:
-
- - input contours can be intersecting, self-intersecting, or degenerate.
-
- - supports a choice of several winding rules for determining which parts
- of the polygon are on the "interior". This makes it possible to do
- CSG operations on polygons.
-
- - boundary extraction: instead of tesselating the polygon, returns a
- set of closed contours which separate the interior from the exterior.
-
- - returns the output as a small number of triangle fans and strips,
- rather than a list of independent triangles (when possible).
-
- - output is available as an explicit mesh (a quad-edge structure),
- in addition to the normal callback interface.
-
- - the algorithm used is extremely robust.
-
-
-The interface
--------------
-
- The tesselator state is maintained in a "tesselator object".
- These are allocated and destroyed using
-
- GLUtesselator *gluNewTess( void );
- void gluDeleteTess( GLUtesselator *tess );
-
- Several tesselator objects may be used simultaneously.
-
- Inputs
- ------
-
- The input contours are specified with the following routines:
-
- void gluTessBeginPolygon( GLUtesselator *tess );
- void gluTessBeginContour( GLUtesselator *tess );
- void gluTessVertex( GLUtesselator *tess, GLUcoord coords[3], void *data );
- void gluTessEndContour( GLUtesselator *tess );
- void gluTessEndPolygon( GLUtesselator *tess );
-
- Within each BeginPolygon/EndPolygon pair, there can be zero or more
- calls to BeginContour/EndContour. Within each contour, there are zero
- or more calls to gluTessVertex(). The vertices specify a closed
- contour (the last vertex of each contour is automatically linked to
- the first).
-
- "coords" give the coordinates of the vertex in 3-space. For useful
- results, all vertices should lie in some plane, since the vertices
- are projected onto a plane before tesselation. "data" is a pointer
- to a user-defined vertex structure, which typically contains other
- information such as color, texture coordinates, normal, etc. It is
- used to refer to the vertex during rendering.
-
- The library can be compiled in single- or double-precision; the type
- GLUcoord represents either "float" or "double" accordingly. The GLU
- version will be available in double-precision only. Compile with
- GLU_TESS_API_FLOAT defined to get the single-precision version.
-
- When EndPolygon is called, the tesselation algorithm determines
- which regions are interior to the given contours, according to one
- of several "winding rules" described below. The interior regions
- are then tesselated, and the output is provided as callbacks.
-
-
- Rendering Callbacks
- -------------------
-
- Callbacks are specified by the client using
-
- void gluTessCallback( GLUtesselator *tess, GLenum which, void (*fn)());
-
- If "fn" is NULL, any previously defined callback is discarded.
-
- The callbacks used to provide output are: /* which == */
-
- void begin( GLenum type ); /* GLU_TESS_BEGIN */
- void edgeFlag( GLboolean flag ); /* GLU_TESS_EDGE_FLAG */
- void vertex( void *data ); /* GLU_TESS_VERTEX */
- void end( void ); /* GLU_TESS_END */
-
- Any of the callbacks may be left undefined; if so, the corresponding
- information will not be supplied during rendering.
-
- The "begin" callback indicates the start of a primitive; type is one
- of GL_TRIANGLE_STRIP, GL_TRIANGLE_FAN, or GL_TRIANGLES (but see the
- notes on "boundary extraction" below).
-
- It is followed by any number of "vertex" callbacks, which supply the
- vertices in the same order as expected by the corresponding glBegin()
- call. After the last vertex of a given primitive, there is a callback
- to "end".
-
- If the "edgeFlag" callback is provided, no triangle fans or strips
- will be used. When edgeFlag is called, if "flag" is GL_TRUE then each
- vertex which follows begins an edge which lies on the polygon boundary
- (ie. an edge which separates an interior region from an exterior one).
- If "flag" is GL_FALSE, each vertex which follows begins an edge which lies
- in the polygon interior. "edgeFlag" will be called before the first
- call to "vertex".
-
- Other Callbacks
- ---------------
-
- void mesh( GLUmesh *mesh ); /* GLU_TESS_MESH */
-
- - Returns an explicit mesh, represented using the quad-edge structure
- (Guibas/Stolfi '85). Other implementations of this interface might
- use a different mesh structure, so this is available only only as an
- SGI extension. When the mesh is no longer needed, it should be freed
- using
-
- void gluDeleteMesh( GLUmesh *mesh );
-
- There is a brief description of this data structure in the include
- file "mesh.h". For the full details, see L. Guibas and J. Stolfi,
- Primitives for the manipulation of general subdivisions and the
- computation of Voronoi diagrams, ACM Transactions on Graphics,
- 4(2):74-123, April 1985. For an introduction, see the course notes
- for CS348a, "Mathematical Foundations of Computer Graphics",
- available at the Stanford bookstore (and taught during the fall
- quarter).
-
- void error( GLenum errno ); /* GLU_TESS_ERROR */
-
- - errno is one of GLU_TESS_MISSING_BEGIN_POLYGON,
- GLU_TESS_MISSING_END_POLYGON,
- GLU_TESS_MISSING_BEGIN_CONTOUR,
- GLU_TESS_MISSING_END_CONTOUR,
- GLU_TESS_COORD_TOO_LARGE,
- GLU_TESS_NEED_COMBINE_CALLBACK
-
- The first four are obvious. The interface recovers from these
- errors by inserting the missing call(s).
-
- GLU_TESS_COORD_TOO_LARGE says that some vertex coordinate exceeded
- the predefined constant GLU_TESS_MAX_COORD in absolute value, and
- that the value has been clamped. (Coordinate values must be small
- enough so that two can be multiplied together without overflow.)
-
- GLU_TESS_NEED_COMBINE_CALLBACK says that the algorithm detected an
- intersection between two edges in the input data, and the "combine"
- callback (below) was not provided. No output will be generated.
-
-
- void combine( GLUcoord coords[3], void *data[4], /* GLU_TESS_COMBINE */
- GLUcoord weight[4], void **outData );
-
- - When the algorithm detects an intersection, or wishes to merge
- features, it needs to create a new vertex. The vertex is defined
- as a linear combination of up to 4 existing vertices, referenced
- by data[0..3]. The coefficients of the linear combination are
- given by weight[0..3]; these weights always sum to 1.0. All vertex
- pointers are valid even when some of the weights are zero.
- "coords" gives the location of the new vertex.
-
- The user must allocate another vertex, interpolate parameters
- using "data" and "weights", and return the new vertex pointer in
- "outData". This handle is supplied during rendering callbacks.
- For example, if the polygon lies in an arbitrary plane in 3-space,
- and we associate a color with each vertex, the combine callback might
- look like this:
-
- void myCombine( GLUcoord coords[3], VERTEX *d[4],
- GLUcoord w[4], VERTEX **dataOut )
- {
- VERTEX *new = new_vertex();
-
- new->x = coords[0];
- new->y = coords[1];
- new->z = coords[2];
- new->r = w[0]*d[0]->r + w[1]*d[1]->r + w[2]*d[2]->r + w[3]*d[3]->r;
- new->g = w[0]*d[0]->g + w[1]*d[1]->g + w[2]*d[2]->g + w[3]*d[3]->g;
- new->b = w[0]*d[0]->b + w[1]*d[1]->b + w[2]*d[2]->b + w[3]*d[3]->b;
- new->a = w[0]*d[0]->a + w[1]*d[1]->a + w[2]*d[2]->a + w[3]*d[3]->a;
- *dataOut = new;
- }
-
- If the algorithm detects an intersection, then the "combine" callback
- must be defined, and must write a non-NULL pointer into "dataOut".
- Otherwise the GLU_TESS_NEED_COMBINE_CALLBACK error occurs, and no
- output is generated. This is the only error that can occur during
- tesselation and rendering.
-
-
- Control over Tesselation
- ------------------------
-
- void gluTessProperty( GLUtesselator *tess, GLenum which, GLUcoord value );
-
- Properties defined:
-
- - GLU_TESS_WINDING_RULE. Possible values:
-
- GLU_TESS_WINDING_ODD
- GLU_TESS_WINDING_NONZERO
- GLU_TESS_WINDING_POSITIVE
- GLU_TESS_WINDING_NEGATIVE
- GLU_TESS_WINDING_ABS_GEQ_TWO
-
- The input contours parition the plane into regions. A winding
- rule determines which of these regions are inside the polygon.
-
- For a single contour C, the winding number of a point x is simply
- the signed number of revolutions we make around x as we travel
- once around C (where CCW is positive). When there are several
- contours, the individual winding numbers are summed. This
- procedure associates a signed integer value with each point x in
- the plane. Note that the winding number is the same for all
- points in a single region.
-
- The winding rule classifies a region as "inside" if its winding
- number belongs to the chosen category (odd, nonzero, positive,
- negative, or absolute value of at least two). The current GLU
- tesselator implements the "odd" rule. The "nonzero" rule is another
- common way to define the interior. The other three rules are
- useful for polygon CSG operations (see below).
-
- - GLU_TESS_BOUNDARY_ONLY. Values: TRUE (non-zero) or FALSE (zero).
-
- If TRUE, returns a set of closed contours which separate the
- polygon interior and exterior (rather than a tesselation).
- Exterior contours are oriented CCW with respect to the normal,
- interior contours are oriented CW. The GLU_TESS_BEGIN callback
- uses the type GL_LINE_LOOP for each contour.
-
- - GLU_TESS_TOLERANCE. Value: a real number between 0.0 and 1.0.
-
- This specifies a tolerance for merging features to reduce the size
- of the output. For example, two vertices which are very close to
- each other might be replaced by a single vertex. The tolerance
- is multiplied by the largest coordinate magnitude of any input vertex;
- this specifies the maximum distance that any feature can move as the
- result of a single merge operation. If a single feature takes part
- in several merge operations, the total distance moved could be larger.
-
- Feature merging is completely optional; the tolerance is only a hint.
- The implementation is free to merge in some cases and not in others,
- or to never merge features at all. The default tolerance is zero.
-
- The current implementation merges vertices only if they are exactly
- coincident, regardless of the current tolerance. A vertex is
- spliced into an edge only if the implementation is unable to
- distinguish which side of the edge the vertex lies on.
- Two edges are merged only when both endpoints are identical.
-
-
- void gluTessNormal( GLUtesselator *tess,
- GLUcoord x, GLUcoord y, GLUcoord z )
-
- - Lets the user supply the polygon normal, if known. All input data
- is projected into a plane perpendicular to the normal before
- tesselation. All output triangles are oriented CCW with
- respect to the normal (CW orientation can be obtained by
- reversing the sign of the supplied normal). For example, if
- you know that all polygons lie in the x-y plane, call
- "gluTessNormal(tess, 0.0, 0.0, 1.0)" before rendering any polygons.
-
- - If the supplied normal is (0,0,0) (the default value), the
- normal is determined as follows. The direction of the normal,
- up to its sign, is found by fitting a plane to the vertices,
- without regard to how the vertices are connected. It is
- expected that the input data lies approximately in plane;
- otherwise projection perpendicular to the computed normal may
- substantially change the geometry. The sign of the normal is
- chosen so that the sum of the signed areas of all input contours
- is non-negative (where a CCW contour has positive area).
-
- - The supplied normal persists until it is changed by another
- call to gluTessNormal.
-
-
- Backward compatibility with the GLU tesselator
- ----------------------------------------------
-
- The preferred interface is the one described above. The following
- routines are obsolete, and are provided only for backward compatibility:
-
- typedef GLUtesselator GLUtriangulatorObj; /* obsolete name */
-
- void gluBeginPolygon( GLUtesselator *tess );
- void gluNextContour( GLUtesselator *tess, GLenum type );
- void gluEndPolygon( GLUtesselator *tess );
-
- "type" is one of GLU_EXTERIOR, GLU_INTERIOR, GLU_CCW, GLU_CW, or
- GLU_UNKNOWN. It is ignored by the current GLU tesselator.
-
- GLU_BEGIN, GLU_VERTEX, GLU_END, GLU_ERROR, and GLU_EDGE_FLAG are defined
- as synonyms for GLU_TESS_BEGIN, GLU_TESS_VERTEX, GLU_TESS_END,
- GLU_TESS_ERROR, and GLU_TESS_EDGE_FLAG.
-
-
-Polygon CSG operations
-----------------------
-
- The features of the tesselator make it easy to find the union, difference,
- or intersection of several polygons.
-
- First, assume that each polygon is defined so that the winding number
- is 0 for each exterior region, and 1 for each interior region. Under
- this model, CCW contours define the outer boundary of the polygon, and
- CW contours define holes. Contours may be nested, but a nested
- contour must be oriented oppositely from the contour that contains it.
-
- If the original polygons do not satisfy this description, they can be
- converted to this form by first running the tesselator with the
- GLU_TESS_BOUNDARY_ONLY property turned on. This returns a list of
- contours satisfying the restriction above. By allocating two
- tesselator objects, the callbacks from one tesselator can be fed
- directly to the input of another.
-
- Given two or more polygons of the form above, CSG operations can be
- implemented as follows:
-
- Union
- Draw all the input contours as a single polygon. The winding number
- of each resulting region is the number of original polygons
- which cover it. The union can be extracted using the
- GLU_TESS_WINDING_NONZERO or GLU_TESS_WINDING_POSITIVE winding rules.
- Note that with the nonzero rule, we would get the same result if
- all contour orientations were reversed.
-
- Intersection (two polygons at a time only)
- Draw a single polygon using the contours from both input polygons.
- Extract the result using GLU_TESS_WINDING_ABS_GEQ_TWO. (Since this
- winding rule looks at the absolute value, reversing all contour
- orientations does not change the result.)
-
- Difference
-
- Suppose we want to compute A \ (B union C union D). Draw a single
- polygon consisting of the unmodified contours from A, followed by
- the contours of B,C,D with the vertex order reversed (this changes
- the winding number of the interior regions to -1). To extract the
- result, use the GLU_TESS_WINDING_POSITIVE rule.
-
- If B,C,D are the result of a GLU_TESS_BOUNDARY_ONLY call, an
- alternative to reversing the vertex order is to reverse the sign of
- the supplied normal. For example in the x-y plane, call
- gluTessNormal( tess, 0.0, 0.0, -1.0 ).
-
-
-Performance
------------
-
- The tesselator is not intended for immediate-mode rendering; when
- possible the output should be cached in a user structure or display
- list. General polygon tesselation is an inherently difficult problem,
- especially given the goal of extreme robustness.
-
- The implementation makes an effort to output a small number of fans
- and strips; this should improve the rendering performance when the
- output is used in a display list.
-
- Single-contour input polygons are first tested to see whether they can
- be rendered as a triangle fan with respect to the first vertex (to
- avoid running the full decomposition algorithm on convex polygons).
- Non-convex polygons may be rendered by this "fast path" as well, if
- the algorithm gets lucky in its choice of a starting vertex.
-
- For best performance follow these guidelines:
-
- - supply the polygon normal, if available, using gluTessNormal().
- This represents about 10% of the computation time. For example,
- if all polygons lie in the x-y plane, use gluTessNormal(tess,0,0,1).
-
- - render many polygons using the same tesselator object, rather than
- allocating a new tesselator for each one. (In a multi-threaded,
- multi-processor environment you may get better performance using
- several tesselators.)
-
-
-Comparison with the GLU tesselator
-----------------------------------
-
- On polygons which make it through the "fast path", the tesselator is
- 3 to 5 times faster than the GLU tesselator.
-
- On polygons which don't make it through the fast path (but which don't
- have self-intersections or degeneracies), it is about 2 times slower.
-
- On polygons with self-intersections or degeneraces, there is nothing
- to compare against.
-
- The new tesselator generates many more fans and strips, reducing the
- number of vertices that need to be sent to the hardware.
-
- Key to the statistics:
-
- vert number of input vertices on all contours
- cntr number of input contours
- tri number of triangles in all output primitives
- strip number of triangle strips
- fan number of triangle fans
- ind number of independent triangles
- ms number of milliseconds for tesselation
- (on a 150MHz R4400 Indy)

-This is only a very brief overview. There is quite a bit of
-additional documentation in the source code itself.

-
-Goals of robust tesselation
----------------------------
-
-The tesselation algorithm is fundamentally a 2D algorithm. We
-initially project all data into a plane; our goal is to robustly
-tesselate the projected data. The same topological tesselation is
-then applied to the input data.
-
-Topologically, the output should always be a tesselation. If the
-input is even slightly non-planar, then some triangles will
-necessarily be back-facing when viewed from some angles, but the goal
-is to minimize this effect.
-
-The algorithm needs some capability of cleaning up the input data as
-well as the numerical errors in its own calculations. One way to do
-this is to specify a tolerance as defined above, and clean up the
-input and output during the line sweep process. At the very least,
-the algorithm must handle coincident vertices, vertices incident to an
-edge, and coincident edges.
-
-
-Phases of the algorithm
------------------------
-
-1. Find the polygon normal N.
-2. Project the vertex data onto a plane. It does not need to be
- perpendicular to the normal, eg. we can project onto the plane
- perpendicular to the coordinate axis whose dot product with N
- is largest.
-3. Using a line-sweep algorithm, partition the plane into x-monotone
- regions. Any vertical line intersects an x-monotone region in
- at most one interval.
-4. Triangulate the x-monotone regions.
-5. Group the triangles into strips and fans.
-
-
-Finding the normal vector
--------------------------
-
-A common way to find a polygon normal is to compute the signed area
-when the polygon is projected along the three coordinate axes. We
-can't do this, since contours can have zero area without being
-degenerate (eg. a bowtie).
-
-We fit a plane to the vertex data, ignoring how they are connected
-into contours. Ideally this would be a least-squares fit; however for
-our purpose the accuracy of the normal is not important. Instead we
-find three vertices which are widely separated, and compute the normal
-to the triangle they form. The vertices are chosen so that the
-triangle has an area at least 1/sqrt(3) times the largest area of any
-triangle formed using the input vertices.
-
-The contours do affect the orientation of the normal; after computing
-the normal, we check that the sum of the signed contour areas is
-non-negative, and reverse the normal if necessary.
-
-
-Projecting the vertices
------------------------
-
-We project the vertices onto a plane perpendicular to one of the three
-coordinate axes. This helps numerical accuracy by removing a
-transformation step between the original input data and the data
-processed by the algorithm. The projection also compresses the input
-data; the 2D distance between vertices after projection may be smaller
-than the original 2D distance. However by choosing the coordinate
-axis whose dot product with the normal is greatest, the compression
-factor is at most 1/sqrt(3).
-
-Even though the *accuracy* of the normal is not that important (since
-we are projecting perpendicular to a coordinate axis anyway), the
-*robustness* of the computation is important. For example, if there
-are many vertices which lie almost along a line, and one vertex V
-which is well-separated from the line, then our normal computation
-should involve V otherwise the results will be garbage.
-
-The advantage of projecting perpendicular to the polygon normal is
-that computed intersection points will be as close as possible to
-their ideal locations. To get this behavior, define TRUE_PROJECT.
-
-
-The Line Sweep
---------------
-
-There are three data structures: the mesh, the event queue, and the
-edge dictionary.
-
-The mesh is a "quad-edge" data structure which records the topology of
-the current decomposition; for details see the include file "mesh.h".
-
-The event queue simply holds all vertices (both original and computed
-ones), organized so that we can quickly extract the vertex with the
-minimum x-coord (and among those, the one with the minimum y-coord).
-
-The edge dictionary describes the current intersection of the sweep
-line with the regions of the polygon. This is just an ordering of the
-edges which intersect the sweep line, sorted by their current order of
-intersection. For each pair of edges, we store some information about
-the monotone region between them -- these are call "active regions"
-(since they are crossed by the current sweep line).
-
-The basic algorithm is to sweep from left to right, processing each
-vertex. The processed portion of the mesh (left of the sweep line) is
-a planar decomposition. As we cross each vertex, we update the mesh
-and the edge dictionary, then we check any newly adjacent pairs of
-edges to see if they intersect.
-
-A vertex can have any number of edges. Vertices with many edges can
-be created as vertices are merged and intersection points are
-computed. For unprocessed vertices (right of the sweep line), these
-edges are in no particular order around the vertex; for processed
-vertices, the topological ordering should match the geometric ordering.
-
-The vertex processing happens in two phases: first we process are the
-left-going edges (all these edges are currently in the edge
-dictionary). This involves:
-
- - deleting the left-going edges from the dictionary;
- - relinking the mesh if necessary, so that the order of these edges around
- the event vertex matches the order in the dictionary;
- - marking any terminated regions (regions which lie between two left-going
- edges) as either "inside" or "outside" according to their winding number.
-
-When there are no left-going edges, and the event vertex is in an
-"interior" region, we need to add an edge (to split the region into
-monotone pieces). To do this we simply join the event vertex to the
-rightmost left endpoint of the upper or lower edge of the containing
-region.
-
-Then we process the right-going edges. This involves:
-
- - inserting the edges in the edge dictionary;
- - computing the winding number of any newly created active regions.
- We can compute this incrementally using the winding of each edge
- that we cross as we walk through the dictionary.
- - relinking the mesh if necessary, so that the order of these edges around
- the event vertex matches the order in the dictionary;
- - checking any newly adjacent edges for intersection and/or merging.
-
-If there are no right-going edges, again we need to add one to split
-the containing region into monotone pieces. In our case it is most
-convenient to add an edge to the leftmost right endpoint of either
-containing edge; however we may need to change this later (see the
-code for details).
-
-
-Invariants
-----------
-
-These are the most important invariants maintained during the sweep.
-We define a function VertLeq(v1,v2) which defines the order in which
-vertices cross the sweep line, and a function EdgeLeq(e1,e2; loc)
-which says whether e1 is below e2 at the sweep event location "loc".
-This function is defined only at sweep event locations which lie
-between the rightmost left endpoint of {e1,e2}, and the leftmost right
-endpoint of {e1,e2}.
-
-Invariants for the Edge Dictionary.
-
- - Each pair of adjacent edges e2=Succ(e1) satisfies EdgeLeq(e1,e2)
- at any valid location of the sweep event.
- - If EdgeLeq(e2,e1) as well (at any valid sweep event), then e1 and e2
- share a common endpoint.
- - For each e in the dictionary, e->Dst has been processed but not e->Org.
- - Each edge e satisfies VertLeq(e->Dst,event) && VertLeq(event,e->Org)
- where "event" is the current sweep line event.
- - No edge e has zero length.
- - No two edges have identical left and right endpoints.
-
-Invariants for the Mesh (the processed portion).
-
- - The portion of the mesh left of the sweep line is a planar graph,
- ie. there is *some* way to embed it in the plane.
- - No processed edge has zero length.
- - No two processed vertices have identical coordinates.
- - Each "inside" region is monotone, ie. can be broken into two chains
- of monotonically increasing vertices according to VertLeq(v1,v2)
- - a non-invariant: these chains may intersect (slightly) due to
- numerical errors, but this does not affect the algorithm's operation.
-
-Invariants for the Sweep.
-
- - If a vertex has any left-going edges, then these must be in the edge
- dictionary at the time the vertex is processed.
- - If an edge is marked "fixUpperEdge" (it is a temporary edge introduced
- by ConnectRightVertex), then it is the only right-going edge from
- its associated vertex. (This says that these edges exist only
- when it is necessary.)
-
-
-Robustness
-----------
-
-The key to the robustness of the algorithm is maintaining the
-invariants above, especially the correct ordering of the edge
-dictionary. We achieve this by:
-
- 1. Writing the numerical computations for maximum precision rather
- than maximum speed.
-
- 2. Making no assumptions at all about the results of the edge
- intersection calculations -- for sufficiently degenerate inputs,
- the computed location is not much better than a random number.
-
- 3. When numerical errors violate the invariants, restore them
- by making *topological* changes when necessary (ie. relinking
- the mesh structure).
-
-
-Triangulation and Grouping
---------------------------
-
-We finish the line sweep before doing any triangulation. This is
-because even after a monotone region is complete, there can be further
-changes to its vertex data because of further vertex merging.
-
-After triangulating all monotone regions, we want to group the
-triangles into fans and strips. We do this using a greedy approach.
-The triangulation itself is not optimized to reduce the number of
-primitives; we just try to get a reasonable decomposition of the
-computed triangulation.

- * (Onext) and around the left face (Lnext). There is also a "next"
- * pointer for the global edge list (see below).
- *
- * The notation used for mesh navigation:
- * Sym = the mate of a half-edge (same edge, but opposite direction)
- * Onext = edge CCW around origin vertex (keep same origin)
- * Dnext = edge CCW around destination vertex (keep same dest)
- * Lnext = edge CCW around left face (dest becomes new origin)
- * Rnext = edge CCW around right face (origin becomes new dest)
- *
- * "prev" means to substitute CW for CCW in the definitions above.
- *
- * The mesh keeps global lists of all vertices, faces, and edges,
- * stored as doubly-linked circular lists with a dummy header node.
- * The mesh stores pointers to these dummy headers (vHead, fHead, eHead).
- *
- * The circular edge list is special; since half-edges always occur
- * in pairs (e and e->Sym), each half-edge stores a pointer in only
- * one direction. Starting at eHead and following the e->next pointers
- * will visit each *edge* once (ie. e or e->Sym, but not both).
- * e->Sym stores a pointer in the opposite direction, thus it is
- * always true that e->Sym->next->Sym->next == e.
- *
- * Each vertex has a pointer to next and previous vertices in the
- * circular list, and a pointer to a half-edge with this vertex as
- * the origin (NULL if this is the dummy header). There is also a
- * field "data" for client data.
- *
- * Each face has a pointer to the next and previous faces in the
- * circular list, and a pointer to a half-edge with this face as
- * the left face (NULL if this is the dummy header). There is also
- * a field "data" for client data.
- *
- * Note that what we call a "face" is really a loop; faces may consist
- * of more than one loop (ie. not simply connected), but there is no
- * record of this in the data structure. The mesh may consist of
- * several disconnected regions, so it may not be possible to visit
- * the entire mesh by starting at a half-edge and traversing the edge
- * structure.
- *
- * The mesh does NOT support isolated vertices; a vertex is deleted along
- * with its last edge. Similarly when two faces are merged, one of the
- * faces is deleted (see __gl_meshDelete below). For mesh operations,
- * all face (loop) and vertex pointers must not be NULL. However, once
- * mesh manipulation is finished, __gl_MeshZapFace can be used to delete
- * faces of the mesh, one at a time. All external faces can be "zapped"
- * before the mesh is returned to the client; then a NULL face indicates
- * a region which is not part of the output polygon.

-/* The mesh operations below have three motivations: completeness,
- * convenience, and efficiency. The basic mesh operations are MakeEdge,
- * Splice, and Delete. All the other edge operations can be implemented
- * in terms of these. The other operations are provided for convenience
- * and/or efficiency.
- *
- * When a face is split or a vertex is added, they are inserted into the
- * global list *before* the existing vertex or face (ie. e->Org or e->Lface).
- * This makes it easier to process all vertices or faces in the global lists
- * without worrying about processing the same data twice. As a convenience,
- * when a face is split, the "inside" flag is copied from the old face.
- * Other internal data (v->data, v->activeRegion, f->data, f->marked,
- * f->trail, e->winding) is set to zero.
- *
- * ********************** Basic Edge Operations **************************
- *
- * __gl_meshMakeEdge( mesh ) creates one edge, two vertices, and a loop.
- * The loop (face) consists of the two new half-edges.
- *
- * __gl_meshSplice( eOrg, eDst ) is the basic operation for changing the
- * mesh connectivity and topology. It changes the mesh so that
- * eOrg->Onext <- OLD( eDst->Onext )
- * eDst->Onext <- OLD( eOrg->Onext )
- * where OLD(...) means the value before the meshSplice operation.
- *
- * This can have two effects on the vertex structure:
- * - if eOrg->Org != eDst->Org, the two vertices are merged together
- * - if eOrg->Org == eDst->Org, the origin is split into two vertices
- * In both cases, eDst->Org is changed and eOrg->Org is untouched.
- *
- * Similarly (and independently) for the face structure,
- * - if eOrg->Lface == eDst->Lface, one loop is split into two
- * - if eOrg->Lface != eDst->Lface, two distinct loops are joined into one
- * In both cases, eDst->Lface is changed and eOrg->Lface is unaffected.
- *
- * __gl_meshDelete( eDel ) removes the edge eDel. There are several cases:
- * if (eDel->Lface != eDel->Rface), we join two loops into one; the loop
- * eDel->Lface is deleted. Otherwise, we are splitting one loop into two;
- * the newly created loop will contain eDel->Dst. If the deletion of eDel
- * would create isolated vertices, those are deleted as well.
- *
- * ********************** Other Edge Operations **************************
- *
- * __gl_meshAddEdgeVertex( eOrg ) creates a new edge eNew such that
- * eNew == eOrg->Lnext, and eNew->Dst is a newly created vertex.
- * eOrg and eNew will have the same left face.
- *
- * __gl_meshSplitEdge( eOrg ) splits eOrg into two edges eOrg and eNew,
- * such that eNew == eOrg->Lnext. The new vertex is eOrg->Dst == eNew->Org.
- * eOrg and eNew will have the same left face.
- *
- * __gl_meshConnect( eOrg, eDst ) creates a new edge from eOrg->Dst
- * to eDst->Org, and returns the corresponding half-edge eNew.
- * If eOrg->Lface == eDst->Lface, this splits one loop into two,
- * and the newly created loop is eNew->Lface. Otherwise, two disjoint
- * loops are merged into one, and the loop eDst->Lface is destroyed.
- *
- * ************************ Other Operations *****************************
- *
- * __gl_meshNewMesh() creates a new mesh with no edges, no vertices,
- * and no loops (what we usually call a "face").
- *
- * __gl_meshUnion( mesh1, mesh2 ) forms the union of all structures in
- * both meshes, and returns the new mesh (the old meshes are destroyed).
- *
- * __gl_meshDeleteMesh( mesh ) will free all storage for any valid mesh.
- *
- * __gl_meshZapFace( fZap ) destroys a face and removes it from the
- * global face list. All edges of fZap will have a NULL pointer as their
- * left face. Any edges which also have a NULL pointer as their right face
- * are deleted entirely (along with any isolated vertices this produces).
- * An entire mesh can be deleted by zapping its faces, one at a time,
- * in any order. Zapped faces cannot be used in further mesh operations!
- *
- * __gl_meshCheckMesh( mesh ) checks a mesh for self-consistency.

-/* __gl_meshTessellateMonoRegion( face ) tessellates a monotone region
- * (what else would it do??) The region must consist of a single
- * loop of half-edges (see mesh.h) oriented CCW. "Monotone" in this
- * case means that any vertical line intersects the interior of the
- * region in a single interval.
- *
- * Tessellation consists of adding interior edges (actually pairs of
- * half-edges), to split the region into non-overlapping triangles.
- *
- * __gl_meshTessellateInterior( mesh ) tessellates each region of
- * the mesh which is marked "inside" the polygon. Each such region
- * must be monotone.
- *
- * __gl_meshDiscardExterior( mesh ) zaps (ie. sets to NULL) all faces
- * which are not marked "inside" the polygon. Since further mesh operations
- * on NULL faces are not allowed, the main purpose is to clean up the
- * mesh so that exterior loops are not represented in the data structure.
- *
- * __gl_meshSetWindingNumber( mesh, value, keepOnlyBoundary ) resets the
- * winding numbers on all edges so that regions marked "inside" the
- * polygon have a winding number of "value", and regions outside
- * have a winding number of 0.
- *
- * If keepOnlyBoundary is TRUE, it also deletes all edges which do not
- * separate an interior region from an exterior one.
