thx for the info. Why don't they implement it if it's declared? Annoying.
If it's the gl drivers which do the software fallback, should that not work in
my c code too? I'm just doing basic straightforward C OpenGL. Does QC do
something to enable the software fallback? Is it related to the gl context
creation? (sorry if this is drifting off-list)
Cheers,
