Classes
class	float4
	Representation of an array of 4 floats. Convenient for passing COLOR + alpha, Wpt, or Wvec to OpenGL:. More...
class	float3
	Representation of an array of 3 floats. Convenient for passing a Wpt, Wvec, or COLOR to OpenGL. More...
class	float2
	Representation of an array of 2 floats. Convenient for passing a PIXEL or other 2D type to OpenGL. More...
class	float16
	Representation of an array of 16 floats. Really only seems applicable for Wtransf, thus that is the only variety provided. More...
Functions
GLenum	light_i (int i)
	Convenience function. E.g.: light_i(0) returns GL_LIGHT0.
void	GL_COL (CCOLOR &c, double a)
	Send a color and alpha value to OpenGL.
void	GL_MAT_COLOR (GLenum face, GLenum pname, const COLOR &c, double a)
	Set OpenGL material color values given a COLOR and an alpha value.
