DDraw over WineD3D - Indexed colour visuals

[Adam Luchjenbroers]

I've been using and tracking Stefan Dossinger's work re: DDraw over WineD3D 
and decided try and find out if IWineD3DSurface was far enough along to be 
able to be used in place of IWineX11Surface for 2d applications (Hopefully to 
eliminate depth conversion issues).

Short answer, no.

Long answer, Screen displays blank, trace log shows that glReadPixels at line 
615 in wined3d\surface.c (LockRect) is failing with error 
GL_INVALID_OPERATION. Further investigation reveals that this is because 
glFormat is GL_COLOR_INDEX, yet the display is an RGB visual (presumably 
because an indexed colour visual was not available, and this buffer is 
connected directly to the screen).

I figured I'd look to the people already familiar with the WineD3D\DDraw 
codebase before I tried to figure out my own solution.
