 r300_render.c
Log Message:
For some reason we need r300Flush when using textures. Perhaps the problem
is
with BITBLT_MULTI call ?
I haven't looked at how texturing is implemented yet, but are the GPU caches
flushed after the texture upload and before the rendering? I think
r300Flush() does this implicitly.
Good point, I have not paid any attention to caches.
However, r300Flush works around a lockup which occurs if it is not 
present. I would normally expect that not touching the cache would simply 
mean we paint the wrong thing.

Of course, it might be that cache management is simply broken on r300 and 
later cards.

                  thank you !
