its pixmap" patch be selectable at runtime

The patch works wonderfully! Thank you very much!
The only thing is that you have to modify the Makefile.in in the opengl32
directory and add "ntdll" to the libs list.

I don't think it would be that hard to realize. Right now we have the
ENTER_GL() macro that gets called before each opengl call (see opengl_ext.c
and norm.c) where the check and sync occurs. One solution would be to make
two enter_gl functions -- one with the check and one without, and hardcode
some database with the function list in the script that generates the files.
This patch does already a great job for fixing Huw's regressions, and me and
many Wine users would greatly appreciate its merge into Wine tree.
