[SDL] SDL_SetVideoMode problem

[David Olsen]

This will work well:
SDL_putenv("SDL_VIDEO_CENTERED=1");

However, it will only work for the first window that is initialized. I mean 
that if you start with a splash screen which is say at 100x100, and then 
after loading all your stuff, you change the window size to 450x450, the 
upper left corner will remain in the same spot. REALLY annoying.

This can be resolved by having the SDL_VIDEO_CENTERED = 1 as a global 
environmental variable (set in the OS's global env var's), but that's a 
stretch to ask the end-user to do such a thing.

I find that even if I call SDL_putenv("SDL_VIDEO_CENTERED=1") again before 
making the 2nd window, it still behaves in the annoying manner of not 
actually being centered.

If all you do is use one window size throughout, though, you're set!
Hope this helps!
