newtree/include/glquake.h
Jeff Teunissen fc005fc215 Cleanup of extensions, they are no longer defined in glquake.h. In 
addition, removed support (for now) for SGIS and EXT multitexture. It
allowed me to enhance support for ARB multitexture, which is better anyway
(especially for Radeon, but that won't get special support yet until we
need a third texture pass).

Updated the Unix 8-bit GL code to be more like the Windows version, which
may work better. It still defaults off, because many drivers have bugs in
their handling of the shared texture palette extension.
