From: "Ryan C. Gordon"
Subject: [SDL] Minor X11 hack:
Here's a patch to center a newly-created, non-fullscreen X11 window.
While this may or may not be suitable for adding to SDL officially, I
didn't want to put any Xlib dependencies in my code directly.
To use:
- Apply patch/rebuild.
- export SDL_WINDOW_POS=center
- Call SDL_SetVideoMode as needed.
(Ideally, this could be expanded to handle other commands like
SDL_WINDOW_POS=20x190, etc, and could be implemented for other targets,
but this is really a hack to avoid API changes).
