I believe I'm using the generic Win2K drivers. My video adapter is "Trident
CyberBlade i-7 1024x768x32, 60 Hz"... It *says* it's accelerated, but I
think it's just accelerated for bitblt and other 2-d stuff; 3-d has never
been fast on this box. And all versions of Windows NT have had a hard time
with making opengl fast due to the hardware abstraction layer...

I've uploaded it to http://www.sproat.us/ldglite-test.zip

Perhaps another alternative is to use the Tk toolkit widgets? AFAIK it is
available pre-compiled and in source form for a ton of platforms including
Linux, Mac, Win32, FreeBSD, etc. -- see

Having it as an option would be awesome.
