SDL/GL: hotswap_gfx_mode (win32 and MacOS)
|Reported by:||SF/luke_br||Owned by:||Kirben|
Untested hotswap_gfx_mode() mode for Win32 and MacOS.
Also, there is a fix for the shaking in window mode with
the game fitting the whole window (i hope it doesn't crash
anymore on win32).
I have just tested it on Linux.
