Title: SDL: Fixed antialiasing fallback for less tolerant OpenGL drivers. Fix #407

It's still not a perfect solution, but at least it provides some kind of fallback on Linux as mentioned in bug #407 (and possibly on some other drivers) if the selected antialiasing mode is not supported. It also tries to apply AA if it falls back to 16-bit mode.

If the selected 32-bit with AA is not supported, it tries 32-bit without AA, then 16-bit with AA, then 16-bit without AA as a last resort.
