[SDL] BUG: changing video mode in opengl + windows

[Hibernatus]

Hi,

In WIN_GL_SetupWindow (SDL12/src/video/wincommon/SDL_wingl.c) you call 
WIN_GL_ResetWindow when SetPixelFormat fails.
WIN_GL_ResetWindow cannot properly work in its current state, because there 
are several things to update once you've created a new window. At least 
DirectInput doesn't work anymore here (which is somewhat annoying for the 
player :).
I think you can simply remove that function. Many games don't try to 
recover from that exception, that's why the newest ATI drivers emulate 16 
bpp display in 32 bpp mode so the error never occurs (but the games may run 
much slower).

Having SDL_SetVideoMode return NULL would be better than actually setting 
the video mode and losing focus, directinput and maybe directsound too. It 
also made my previous drivers crash (when switching from 32 bpp windowed to 
16 bpp fullscreen).

Thanks in advance :)
