Subject: [SDL][PATCH] 2 patches for sdl
Here are 2 patches for SDL:
- One is to put the dummy video drivers at the end of the
video drivers list. It gave me problems, when
SDL_VIDEODRIVER is not set, and the dummy driver is used
instead of the platform's driver, just because it is
always available. So the dummy driver must always be at
the end of the list. I suppose picogui and dc video
drivers also don't work.
