  1. Use XRandR and Xinerama to get display info 

    Linux specific. Solves a problem with fullscreen behaviour on multiple-monitor systems.

On Linux, default X11 behaviour seems to describe multiple monitors as a single virtual display (stretched across all physical monitors), so for example it might describe a pair of 1920x1080 monitors as a single 3840x1080 display. Full-screen SDL windows will therefore attempt to cover that 3840x1080 area and stretch across all displays instead of expanding to a single physical screen as they do on Windows and OS X.

SDL_x11modes.c appears to rely on XRandR (or possibly Xinerama) to get information on distinct screens within that virtual display. After enabling both here, fullscreen windows in Linux correctly take full screen on a single monitor.

Compiling requires additional packages libxrandr-dev, libxinerama-dev and a -clean build.
