ups

the aspect thing should be handled by the vf layer. not vo.
(since filters may resize/scale/rotate the image etc)
the vo drivers should only export (in vo struct) the screen size and aspect.
(this part still missing, patch welcomed)

Imho not. AT least in g1, gui had its own control of vo window, instead of
using x11_common.c functions. I thought that in g2 I let the UI to handle
the windows, but i provide a default/fallback implementation in x11_util

If gui coders says they want to use those funcs, then we can re-thing the
APIs.

shit

huh?

resizing is handled by vf layer, ecept when the vo driver support some kind
of external (ie not swscaler) rescaling, in sdl or hardware.

you should read libvo2.txt before hack in more globals ;)
