Depends on the vo. xv takes an unscaled image and does scale+display in
hardware, so there the OSD resolution must match video resolution given
to vo. OTOH gl can take an image, draw it scaled in graphics memory, and
then draw the OSD at the scaled resolution if desired (which is useful
if the video is low resolution and you want to have a higher-resolution
OSD).
