Hi!
Attached patch allows to use new NVIDIA VDPAU high quality scaling with
latest hardware.
If nobody objects, I will apply together with a configure patch to require
driver version 190 that implements the feature.

Forces the use of the VDPAU mixer, which implements all above options (default).
Use noforce\-mixer to allow displaying BGRA colorspace.
