OpenGL Extensions - blend

blend_minmax

Produces the minimum (or maximum) color components of the source and destination colors.

One of several extensions that use a new procedure that enables the respecification of the entire blend equation:


	void glBlendEquationEXT(enum mode);


	FUNC_ADD_EXT		C = (Cs * S) + (Cd * D)
	MIN_EXT			C = min (Cs, Cd)
	MAX_EXT			C = max (Cs, Cd)
