vo_opengl: don't enable PBOs with opengl-hq

Browse Source 
The speed advantages are marginal (at least with the way it's currently
used), and it might actually be slower on some drivers, like Mesa.

``pbo``
Enable use of PBOs. This is faster, but can sometimes lead to sporadic
and temporary image corruption.
Enable use of PBOs. This is slightly faster, but can sometimes lead to
sporadic and temporary image corruption (in theory, because reupload
is not retried when it fails), and perhaps actually triggers slower
paths with drivers that don't support PBOs properly.
``dither-depth=<N|no|auto>``
Set dither target depth to N. Default: no.

This is equivalent to::
--vo=opengl:lscale=lanczos2:dither-depth=auto:pbo:fbo-format=rgb16
--vo=opengl:lscale=lanczos2:dither-depth=auto:fbo-format=rgb16
Note that some cheaper LCDs do dithering that gravely interferes with
``opengl``'s dithering. Disabling dithering with ``dither-depth=no`` helps.
