 New Procedures and Functions
 
     void MatrixLoadfCHROMIUM(enum matrixMode, float* matrix);
 
     Takes a pointer to a 4x4 matrix stored in column-major order as 16
     consecutive floating-point values. The matrixMode specifies which
     matrix, MODELVIEW_CHROMIUM or PROJECTION_CHROMIUM is used.
 
     The funcition specifies either modelview or projection matrix
     to be used with path rendering API calls.
 
     void MatrixLoadIdentityCHROMIUM(enum matrixMode);
 
     Effectively calls MatrixLoadf with the identity matrix.
