Subject: [SDL] [PATCH] Switching between fullscreen/windowed on OS X

Hi,

When switching from fullscreen to windowed mode for opengl applications,
the current version of SDL sets an harmless error, regarding usage of a
NULL semaphore. This is due to code which tries to shut down a blitting
thread, which is only started for double buffered 2d video modes, not for
opengl. The attached patch fixes this.
