	/** @class PG_Color

	@short Allows for an abstraction of a particular color.

	The purpose of this is to allow one to create new colors. If one is interested
	in using predefined color constants, see pgcolors.h (note the letter "s" at the end.)
	A PG_Color can be created from an SDL_Color, a Uint32, or RGB based system.
