Regarding the glDisable(GL_BLEND) in the CTXUSAGE_CLEAR setup: You have to 
mark the D3D state dirty in the context when doing that, otherwise blending 
might not be re-enabled properly on the next draw. I also think that 
disabling blending for clearing is orthogonal to the rest of the patch and 
should be done in a separate patch.

Maybe use 0x1 instead of 1? That will make adding new flags beyond 8 clearer.

Otherwise it looks good!
