Subject: [SDL] First patch concerning 4.3 and refresh rates
OK, here's my first draft of the patch for the above subject.
A short explanation:
X 4.3 introduces many more modelines than older versions. This would be
fine, except it introduces many modes with the *same* resolution but
different refresh rates. And SDL won't necessarily pick the one with the
highest refresh rate.
So this patch restores SDL to X 4.2 functionality. That is, there is only
ever one refresh rate *per* resolution, and it is the highest possible.
This functionality can be totally disabled by using the environment
variable 'SDL_VIDEO_X11_USE_ALL_MODES' set equal to 1.
