Adam Strzelecki to SDL Sending a patch for fullscreen Mac OS X SDL 1.3 (SVN) Cocoa mouse position handling. In fullscreen mouse coordinates should be relative to SCREEN not to the window, which doesn't really occupy fullscreen. Without this patch mouse position (especially Y) was totally incorrect (shifted) in fullscreen.
