[WINED3D: Review] Hook software shaders into drawStridedSlow

Tue Jul 4 04:17:29 CDT 2006


I am hoping someone (Stefan?) will help me with testing/review here, 
because I don't have the apps and the disk space to test properly.  This 
changes things in drawStridedSlow, which is an important code path, so 
correctness and performance matter (for non shader apps).

If there is no feedback I'll submit the patch as is.
====================

- split drawStridedSlow into "prepare" and "draw" segments -
  fixed_prepare_draw (vs swshader_prepare_draw), and draw_vertex.

- do not load or unload attribute arrays for software shaders
  make software shaders go through the drawStridedSlow code path

- disable VBOs for software shaders

- delete the old (disabled) swshader hook.
