// In fullscreen mode when SDL is compiled with DGA support, the mouse
// sensitivity often appears to be unusably wrong (typically too low).
// (This seems to be reported almost exclusively on Ubuntu, but can be
// reproduced on Gentoo after explicitly enabling DGA.)
// Disabling the DGA mouse appears to fix that problem, and doesn't
// have any obvious negative effects.
