Fixed bug 3061 - Selecting the dummy video driver on Mac OS X results…

… in an error

Darren Kulp

The dummy video driver is not available on Mac OS X if SDL_VIDEO_OPENGL is set at library compilation time.

In src/video/SDL_video.c, there is a compile-time check in SDL_CreateWindow() for (SDL_VIDEO_OPENGL && __MACOSX__). When it succeeds, SDL_WINDOW_OPENGL is always requested. Since the dummy video driver does not supply an OpenGL implementation, the error "No OpenGL support in video driver" is supplied to the user, and SDL_CreateWindow() is exited early.
