Hi,

I'm working on replacing big chunks of the Wine bitblt code with XRender. This
will in the end also eliminate some DIB bottlenecks because XRender can do
depth conversion, so we don't have to that during a X11DRV_DIB_SetImageBits and
in other places.

It was mentioned in this bug report that text rendering is slow due to a part
of the DIB stuff. Did you perform any profiling e.g. using sysprof/oprofile to
see which functions consume most time? In the report depth conversion isn't
mentioned but I guess that this might be one of the most time consuming parts.
Is this the case? My work might be able to accelerate AutoCad quite a bit (sure
not as much as a complete DIB engine).
