'''OpenGL extension NV.path_rendering

This module customises the behaviour of the 
OpenGL.raw.GLES2.NV.path_rendering to provide a more 
Python-friendly API

Overview (from the spec)
	
	Conventional OpenGL supports rendering images (pixel rectangles and
	bitmaps) and simple geometric primitives (points, lines, polygons).
	
	This extension adds a new rendering paradigm, known as path rendering,
	for rendering filled and stroked paths.  Path rendering is not novel
	but rather a standard part of most resolution-independent 2D rendering
	systems such as Flash, PDF, Silverlight, SVG, Java 2D, Office
	drawings, TrueType fonts, PostScript and its fonts, Quartz 2D, XML
	Paper Specification (XPS), and OpenVG.  What is novel is the ability
	to mix path rendering with arbitrary OpenGL 3D rendering and imaging.
	
	With this extension, path rendering becomes a first-class rendering
	mode within the OpenGL graphics system that can be arbitrarily mixed
	with existing OpenGL rendering and can take advantage of OpenGL's
	existing mechanisms for texturing, programmability, and per-fragment
	operations.
	
	Unlike geometric primitive rendering, paths are specified on a 2D
	(non-projective) plane rather than in 3D (projective) space.
	Even though the path is defined in a 2D plane, every path can
	be transformed into 3D clip space allowing for 3D view frustum &
	user-defined clipping, depth offset, and depth testing in the same
	manner as geometric primitive rendering.
	
	Both geometric primitive rendering and path rendering support
	rasterization of edges defined by line segments; however, path
	rendering also allows path segments to be specified by Bezier (cubic
	or quadratic) curves or partial elliptical arcs.  This allows path
	rendering to define truly curved primitive boundaries unlike the
	straight edges of line and polygon primitives.  Whereas geometric
	primitive rendering requires convex polygons for well-defined
	rendering results, path rendering allows (and encourages!) concave
	and curved outlines to be specified.  These paths are even allowed
	to self-intersect.
	
	When filling closed paths, the winding of paths (counterclockwise
	or clockwise) determines whether pixels are inside or outside of
	the path.
	
	Paths can also be stroked whereby, conceptually, a fixed-width "brush"
	is pulled along the path such that the brush remains orthogonal to
	the gradient of each path segment.  Samples within the sweep of this
	brush are considered inside the stroke of the path.
	
	This extension supports path rendering through a sequence of three
	operations:
	
	    1.  Path specification is the process of creating and updating
	        a path object consisting of a set of path commands and a
	        corresponding set of 2D vertices.
	
	        Path commands can be specified explicitly from path command
	        and coordinate data, parsed from a string based on standard
	        grammars for representing paths, or specified by a particular
	        glyph of standard font representations.  Also new paths can
	        be specified by weighting one or more existing paths so long
	        as all the weighted paths have consistent command sequences.
	
	        Each path object contains zero or more subpaths specified
	        by a sequence of line segments, partial elliptical arcs,
	        and (cubic or quadratic) Bezier curve segments.  Each path
	        may contain multiple subpaths that can be closed (forming
	        a contour) or open.
	
	    2.  Path stenciling is the process of updating the stencil buffer
	        based on a path's coverage transformed into window space.
	
	        Path stenciling can determine either the filled or stroked
	        coverage of a path.
	
	        The details of path stenciling are explained within the core
	        of the specification.
	
	        Stenciling a stroked path supports all the standard
	        embellishments for path stroking such as end caps, join
	        styles, miter limits, dashing, and dash caps.  These stroking
	        properties specified are parameters of path objects.
	
	    3.  Path covering is the process of emitting simple (convex &
	        planar) geometry that (conservatively) "covers" the path's
	        sample coverage in the stencil buffer.  During path covering,
	        stencil testing can be configured to discard fragments not
	        within the actual coverage of the path as determined by
	        prior path stenciling.
	
	        Path covering can cover either the filled or stroked coverage
	        of a path.
	
	        The details of path covering are explained within the core
	        of the specification.
	
	To render a path object into the color buffer, an application specifies
	a path object and then uses a two-step rendering process.  First, the
	path object is stenciled whereby the path object's stroked or filled
	coverage is rasterized into the stencil buffer.  Second, the path object
	is covered whereby conservative bounding geometry for the path is
	transformed and rasterized with stencil testing configured to test against
	the coverage information written to the stencil buffer in the first step
	so that only fragments covered by the path are written during this second
	step.  Also during this second step written pixels typically have
	their stencil value reset (so there's no need for clearing the
	stencil buffer between rendering each path).
	
	Here is an example of specifying and then rendering a five-point
	star and a heart as a path using Scalable Vector Graphics (SVG)
	path description syntax:
	
	    GLuint pathObj = 42;
	    const char *svgPathString =
	      // star
	      "M100,180 L40,10 L190,120 L10,120 L160,10 z"
	      // heart
	      "M300 300 C 100 400,100 200,300 100,500 200,500 400,300 300Z";
	    glPathStringNV(pathObj, GL_PATH_FORMAT_SVG_NV,
	                   (GLsizei)strlen(svgPathString), svgPathString);
	
	Alternatively applications oriented around the PostScript imaging
	model can use the PostScript user path syntax instead:
	
	    const char *psPathString =
	      // star
	      "100 180 moveto"
	      " 40 10 lineto 190 120 lineto 10 120 lineto 160 10 lineto closepath"
	      // heart
	      " 300 300 moveto"
	      " 100 400 100 200 300 100 curveto"
	      " 500 200 500 400 300 300 curveto closepath";
	    glPathStringNV(pathObj, GL_PATH_FORMAT_PS_NV,
	                   (GLsizei)strlen(psPathString), psPathString);
	
	The PostScript path syntax also supports compact and precise binary
	encoding and includes PostScript-style circular arcs.
	
	Or the path's command and coordinates can be specified explicitly:
	
	    static const GLubyte pathCommands[10] =
	      { GL_MOVE_TO_NV, GL_LINE_TO_NV, GL_LINE_TO_NV, GL_LINE_TO_NV,
	        GL_LINE_TO_NV, GL_CLOSE_PATH_NV,
	        'M', 'C', 'C', 'Z' };  // character aliases
	    static const GLshort pathCoords[12][2] =
	      { {100, 180}, {40, 10}, {190, 120}, {10, 120}, {160, 10},
	        {300,300}, {100,400}, {100,200}, {300,100},
	        {500,200}, {500,400}, {300,300} };
	    glPathCommandsNV(pathObj, 10, pathCommands, 24, GL_SHORT, pathCoords);
	
	Before rendering to a window with a stencil buffer, clear the stencil
	buffer to zero and the color buffer to black:
	
	    glClearStencil(0);
	    glClearColor(0,0,0,0);
	    glStencilMask(~0);
	    glClear(GL_COLOR_BUFFER_BIT | GL_STENCIL_BUFFER_BIT);
	
	Use an orthographic path-to-clip-space transform to map the
	[0..500]x[0..400] range of the star's path coordinates to the [-1..1]
	clip space cube:
	
	    glMatrixLoadIdentityEXT(GL_PROJECTION);
	    glMatrixLoadIdentityEXT(GL_MODELVIEW);
	    glMatrixOrthoEXT(GL_MODELVIEW, 0, 500, 0, 400, -1, 1);
	
	Stencil the path:
	
	    glStencilFillPathNV(pathObj, GL_COUNT_UP_NV, 0x1F);
	
	The 0x1F mask means the counting uses modulo-32 arithmetic. In
	principle the star's path is simple enough (having a maximum winding
	number of 2) that modulo-4 arithmetic would be sufficient so the mask
	could be 0x3.  Or a mask of all 1's (~0) could be used to count with
	all available stencil bits.
	
	Now that the coverage of the star and the heart have been rasterized
	into the stencil buffer, cover the path with a non-zero fill style
	(indicated by the GL_NOTEQUAL stencil function with a zero reference
	value):
	
	    glEnable(GL_STENCIL_TEST);
	    glStencilFunc(GL_NOTEQUAL, 0, 0x1F);
	    glStencilOp(GL_KEEP, GL_KEEP, GL_ZERO);
	    glColor3f(1,1,0); // yellow
	    glCoverFillPathNV(pathObj, GL_BOUNDING_BOX_NV);
	
	The result is a yellow star (with a filled center) to the left of
	a yellow heart.
	
	The GL_ZERO stencil operation ensures that any covered samples
	(meaning those with non-zero stencil values) are zero'ed when
	the path cover is rasterized. This allows subsequent paths to be
	rendered without clearing the stencil buffer again.
	
	A similar two-step rendering process can draw a white outline
	over the star and heart.
	
	Before rendering, configure the path object with desirable path
	parameters for stroking.  Specify a wider 6.5-unit stroke and
	the round join style:
	
	    glPathParameteriNV(pathObj, GL_PATH_JOIN_STYLE_NV, GL_ROUND_NV);
	    glPathParameterfNV(pathObj, GL_PATH_STROKE_WIDTH_NV, 6.5);
	
	 Now stencil the path's stroked coverage into the stencil buffer,
	 setting the stencil to 0x1 for all stencil samples within the
	 transformed path.
	
	    glStencilStrokePathNV(pathObj, 0x1, ~0);
	
	 Cover the path's stroked coverage (with a hull this time instead
	 of a bounding box; the choice doesn't really matter here) while
	 stencil testing that writes white to the color buffer and again
	 zero the stencil buffer.
	
	    glColor3f(1,1,1); // white
	    glCoverStrokePathNV(pathObj, GL_CONVEX_HULL_NV);
	
	 In this example, constant color shading is used but the application
	 can specify their own arbitrary shading and/or blending operations,
	 whether with Cg compiled to fragment program assembly, GLSL, or
	 fixed-function fragment processing.
	
	 More complex path rendering is possible such as clipping one path to
	 another arbitrary path.  This is because stencil testing (as well
	 as depth testing, depth bound test, clip planes, and scissoring)
	 can restrict path stenciling.
	
	 Now let's render the word "OpenGL" atop the star and heart.
	
	 First create a sequence of path objects for the glyphs for the
	 characters in "OpenGL":
	
	    GLuint glyphBase = glGenPathsNV(6);
	    const unsigned char *word = "OpenGL";
	    const GLsizei wordLen = (GLsizei)strlen(word);
	    const GLfloat emScale = 2048;  // match TrueType convention
	    GLuint templatePathObject = ~0;  // Non-existent path object
	    glPathGlyphsNV(glyphBase,
	                   GL_SYSTEM_FONT_NAME_NV, "Helvetica", GL_BOLD_BIT_NV,
	                   wordLen, GL_UNSIGNED_BYTE, word,
	                   GL_SKIP_MISSING_GLYPH_NV, ~0, emScale);
	    glPathGlyphsNV(glyphBase,
	                   GL_SYSTEM_FONT_NAME_NV, "Arial", GL_BOLD_BIT_NV,
	                   wordLen, GL_UNSIGNED_BYTE, word,
	                   GL_SKIP_MISSING_GLYPH_NV, ~0, emScale);
	    glPathGlyphsNV(glyphBase,
	                   GL_STANDARD_FONT_NAME_NV, "Sans", GL_BOLD_BIT_NV,
	                   wordLen, GL_UNSIGNED_BYTE, word,
	                   GL_USE_MISSING_GLYPH_NV, ~0, emScale);
	
	Glyphs are loaded for three different fonts in priority order:
	Helvetica first, then Arial, and if neither of those loads, use the
	standard sans-serif font.  If a prior glPathGlyphsNV is successful
	and specifies the path object range, the subsequent glPathGlyphsNV
	commands silently avoid re-specifying the already existent path
	objects.
	
	Now query the (kerned) separations for the word "OpenGL" and build
	a set of horizontal translations advancing each successive glyph by
	its kerning distance with the following glyph.
	
	    GLfloat xtranslate[6+1];  // wordLen+1
	    glGetPathSpacingNV(GL_ACCUM_ADJACENT_PAIRS_NV,
	                       wordLen+1, GL_UNSIGNED_BYTE,
	                       "\000\001\002\003\004\005\005",  // repeat last letter twice
	                       glyphBase,
	                       1.0f, 1.0f,
	                       GL_TRANSLATE_X_NV,
	                       xtranslate);
	
	Next determine the font-wide vertical minimum and maximum for the
	font face by querying the per-font metrics of any one of the glyphs
	from the font face.
	
	    GLfloat yMinMax[2];
	    glGetPathMetricRangeNV(GL_FONT_Y_MIN_BOUNDS_BIT_NV|GL_FONT_Y_MAX_BOUNDS_BIT_NV,
	                           glyphBase, /*count*/1,
	                           2*sizeof(GLfloat),
	                           yMinMax);
	
	Use an orthographic path-to-clip-space transform to map the
	word's bounds to the [-1..1] clip space cube:
	
	    glMatrixLoadIdentityEXT(GL_PROJECTION);
	    glMatrixOrthoEXT(GL_MODELVIEW,
	                     0, xtranslate[6], yMinMax[0], yMinMax[1],
	                     -1, 1);
	
	Stencil the filled paths of the sequence of glyphs for "OpenGL",
	each transformed by the appropriate 2D translations for spacing.
	
	    glStencilFillPathInstancedNV(6, GL_UNSIGNED_BYTE,
	                                 "\000\001\002\003\004\005",
	                                 glyphBase,
	                                 GL_PATH_FILL_MODE_NV, 0xFF,
	                                 GL_TRANSLATE_X_NV, xtranslate);
	
	 Cover the bounding box union of the glyphs with 50% gray.
	
	    glEnable(GL_STENCIL_TEST);
	    glStencilFunc(GL_NOTEQUAL, 0, 0xFF);
	    glStencilOp(GL_KEEP, GL_KEEP, GL_ZERO);
	    glColor3f(0.5,0.5,0.5); // 50% gray
	    glCoverFillPathInstancedNV(6, GL_UNSIGNED_BYTE,
	                               "\000\001\002\003\004\005",
	                               glyphBase,
	                               GL_BOUNDING_BOX_OF_BOUNDING_BOXES_NV,
	                               GL_TRANSLATE_X_NV, xtranslate);
	
	Voila, the word "OpenGL" in gray is now stenciled into the framebuffer.
	
	Instead of solid 50% gray, the cover operation can apply a linear
	gradient that changes from green (RGB=0,1,0) at the top of the word
	"OpenGL" to blue (RGB=0,0,1) at the bottom of "OpenGL":
	
	    GLfloat rgbGen[3][3] = {
	      0, 0, 0,  // red   = constant zero
	      0, 1, 0,  // green = varies with y from bottom (0) to top (1)
	      0, -1, 1  // blue  = varies with y from bottom (1) to top (0)
	    };
	    glPathColorGenNV(GL_PRIMARY_COLOR, GL_PATH_OBJECT_BOUNDING_BOX_NV,
	                     GL_RGB, &rgbGen[0][0]);
	
	Instead of loading just the glyphs for the characters in "OpenGL",
	the entire character set could be loaded.  This allows the characters
	of the string to be mapped (offset by the glyphBase) to path object names.
	A range of glyphs can be loaded like this:
	
	    const int numChars = 256;  // ISO/IEC 8859-1 8-bit character range
	    GLuint glyphBase = glGenPathsNV(numChars);
	    glPathGlyphRangeNV(glyphBase,
	                       GL_SYSTEM_FONT_NAME_NV, "Helvetica", GL_BOLD_BIT_NV,
	                       0, numChars,
	                       GL_SKIP_MISSING_GLYPH_NV, ~0, emScale);
	    glPathGlyphRangeNV(glyphBase,
	                       GL_SYSTEM_FONT_NAME_NV, "Arial", GL_BOLD_BIT_NV,
	                       0, numChars,
	                       GL_SKIP_MISSING_GLYPH_NV, ~0, emScale);
	    glPathGlyphRangeNV(glyphBase,
	                       GL_STANDARD_FONT_NAME_NV, "Sans", GL_BOLD_BIT_NV,
	                       0, numChars,
	                       GL_USE_MISSING_GLYPH_NV, ~0, emScale);
	
	Given a range of glyphs loaded as path objects, (kerned) spacing
	information can now be queried for the string:
	
	    glGetPathSpacingNV(GL_ACCUM_ADJACENT_PAIRS_NV,
	                       7, GL_UNSIGNED_BYTE, "OpenGLL", // repeat L to get final spacing
	                       glyphBase,
	                       1.0f, 1.0f,
	                       GL_TRANSLATE_X_NV,
	                       kerning);
	
	Using the range of glyphs, stenciling and covering the instanced
	paths for "OpenGL" can be done this way:
	
	    glStencilFillPathInstancedNV(6, GL_UNSIGNED_BYTE, "OpenGL",
	                                 glyphBase,
	                                 GL_PATH_FILL_MODE_NV, 0xFF,
	                                 GL_TRANSLATE_X_NV, xtranslate);
	
	    glCoverFillPathInstancedNV(6, GL_UNSIGNED_BYTE, "OpenGL",
	                               glyphBase,
	                               GL_BOUNDING_BOX_OF_BOUNDING_BOXES_NV,
	                               GL_TRANSLATE_X_NV, xtranslate);
	
	The "stencil" and "cover" steps can be combined in a single command:
	
	    glStencilThenCoverFillPathInstancedNV(6, GL_UNSIGNED_BYTE, "OpenGL",
	                                          glyphBase,
	                                          GL_PATH_FILL_MODE_NV, 0xFF,
	                                          GL_BOUNDING_BOX_OF_BOUNDING_BOXES_NV
	                                          GL_TRANSLATE_X_NV, xtranslate);
