[PATCH 2/7] wined3d: Use ARB_internalformat_query2 to check for texture format rendering and blending support, where available.

[Matteo Bruni]

Hrm, I sent the wrong version of the patch, I had actually moved the
depth/stencil check earlier (so yeah, totally agree on that part).
Also you're right about WINED3DFMT_FLAG_RENDERTARGET, for some reason
I thought we were setting that in check_fbo_compat() but it's clearly
not the case.

I'm sending the updated patches in a bit (also dropping patches 5-7
since they are superseded by yours).
