		27	* Revision 1.2 2002/04/23 18:23:32 kschultz
		28	* Fix up alpha buffer handling for Windows.
		29	* - add two new Pixel Format Descriptors that do not have alpha bits to
		30	* mirror the two that do.
		31	* - add logic to wglChoosePixelFormat to match PFD's with respect to alpha.
		32	* - Create/clear software alpha buffer as required.
		33	* Now a wgl or GLUT program can control the creation of a software alpha
		34	* buffer via the PFD or GLUT parms, respectively.
