-v0.1	feb-2002	initial release

-v0.2	feb-2002	+ fast triangle rasterizers

-			+ enabled sw and 1.3 extensions

-			+ hardware acceleration: FreeBE/AF

-			+ single-buffer modes (15-, 16-, and 32-bit)

-			* video mode is set by CreateVisual, not MakeCurrent

-			* internal changes to support multi-buf (unfinished)

-			! fixed some alpha issues... (thanks, Brian)

-			+ glut has now an internal timer

-			* glut changed to support multi-window (unfinished)

-			! minor PC_HW corrections

-v0.3	mar-2002	- removed FreeBE/AF code

-			- removed single-buffer modes

-v0.4	mar-2002	+ dynamic module support
