wm4 b36484063f vo_direct3d: rip out texture video rendering path 
This isn't useful anymore. We have a much better d3d11 renderer in
vo_gpu. D3D11 is available in all supported Windows versions. The
StretchRect path might still be useful for someone (???), and leaving it
at least evades conflict about users who want to keep using this VO for
inexplicable reasons. (Low power usage might be a justified reason, but
still, no.)

Also fuck the win32 platform, it's a heap of stinky shit. Microsoft is
some sort of psycho clown software company. Granted, maybe still better
than much of the rest of Silly Con Valley.
