Ok, that makes total sense. I know Quake/Quake II support Glide,
and the 3D accelerated versions do not run without Glide even if
you have no 3dfx card and just want to use OpenGL with a r128
per se. I'd like to straighten out the 3dfx stuff so it is at
least minimally sane and does its job on it's own, as well as
adding support for Voodoo 1&2 for older games. Just the minimal
kludgework to let the cards survive their useful life. ;o)
No idea where to get started at all with trying to get the Glide
stuff to autoload the right lib... Perused the Mesa source, as
well as the mesa and other 3D source dirs in XFree, but I don't
see anything obvious. Closest I came was
xc/lib/GL/mesa/drv/tdfx/fxdd.c or so...
Any pointers on where to go next? Keep in mind we don't ship
XFree86 mesa due to the need for 3D in 3.3.6 also, but a pure
XFree86 hack could likely be easily plopped into standalone Mesa
as well.
Thanks,
