be achieved setting the 'SepOperation' register to 5; the only problem
with that operation is that by default the source blend function is set
to ONE while the destination blend function is set to INVSRCALPHA.
Actually I am working to find how to change the blend functions and
I suppose the NV4_IMAGE_BLEND_PREMULT (0x67) object should be used to do
that. Since under X11 that object is never used, mapping the registers under windows really could help me to understand how to make it work.
