17 Overview
18
19     This extensions implements path rendering using
20     OpenGL API.

22 New Tokens
23
24     Accepted by the <matrixMode> parameter of MatrixLoadfCHROMIUM and
25     MatrixLoadIdentityCHROMIUM:
26     PATH_MODELVIEW_CHROMIUM                           0x1700
27     PATH_PROJECTION_CHROMIUM                          0x1701

29     Accepted by the <pname> parameter of GetIntegerv,
30     GetFloatv:

35 New Procedures and Functions
36
37     void MatrixLoadfCHROMIUM(enum matrixMode, float* matrix)
38
39     Takes a pointer to a 4x4 matrix stored in column-major order as 16
40     consecutive ï¬‚oating-point values. The matrixMode specifies which
41     matrix, PATH_MODELVIEW_CHROMIUM or PATH_PROJECTION_CHROMIUM is used.
42
43     The funcition specifies either modelview or projection matrix
44     to be used with path rendering API calls.
45
46     void MatrixLoadIdentityCHROMIUM(enum matrixMode)
47
48     Effectively calls MatrixLoadf with the identity matrix.
