7/3 WineD3D: Offer WINED3DUSAGE_QUERY_POSTPIXELSHADER_BLENDING on A16B16R16G16F

[Roderick Colenbrander]

Hi,

At least the Geforce6/7/8 Nvidia drivers advertise WINED3DUSAGE_QUERY_POSTPIXELSHADER_BLENDING on A16B16R16G16F. Geforce6/7 cards support this in hardware and the Nvidia GL drivers expose it too, so offer it. This makes Half-life 2 happy as right now it can't find it and I think this causes it to fail in dx9 mode.

In the future we might want to offer this flag on some more float formats like R32F and friends on Geforce8 hardware which offers hardware blending on much more float formats.

Regards,
Roderick Colenbrander
