vo_opengl: use PBOs by default with opengl-hq

Browse Source 
It's not really known whether PBO use causes problems of any kind (most
likely not). They should slightly increase performance. Use them by
default with "opengl-hq".

Even though PBOs don't have anything to do with rendering quality,
"opengl-hq" provides a test bed for features that should be enabled by
default, but aren't out of fear for regressions.

This is equivalent to:
| --vo=opengl:lscale=lanczos2:fancy-downscaling:dither-depth=0
| --vo=opengl:lscale=lanczos2:fancy-downscaling:dither-depth=0:pbo
Note that some cheaper LCDs do dithering that gravely interferes with
vo_opengl's dithering. Disabling dithering with ``dither-depth=-1`` helps.
