History:
~~~~~~~~
-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
+v1.0 mar-2002 initial release
