[Libva] [RFC] New postprocessing flags to vaPutSurface()

[Gwenole Beauchesne]

Hi,

I have attached new postprocessing flags to expose additional GPU 
features. I am not decided yet for the "scaling-quality" flags naming. The 
rationale behind this is to expose e.g. what AMD marketing calls Avivo HD 
upscaling ("detail enhancement")[1]. NVIDIA has probably similar 
capabilities exposed through VDPAU high-quality scaling options too.

BTW, what additional postprocessing work can the GMA500 chip do?

Comments welcome.

Thanks,
Gwenole.
