[SDL] screen size and bit depth under OpenGL ?

You can't query them, just set the values you want, set the video mode,
and look at the values you get.  The OpenGL drivers will try to provide
the best set of attributes, using your settings as minimums.

I'm don't think it's even possible to query them individually for various
video modes.

See ya,
