No-op GlobalToLocal translations in fullscreen mode
On my MacBook Pro running 10.6, I noticed a small upward bias on mouse movement
in a fullscreen SDL application. The app uses WarpCursor and GetMouseState in a
loop to measure relative movement. I tracked it down to NSWindow's
convertBaseToScreen: routine, which added a 2-pixel offset on the Y coordinate
instead of the expected (+0,+0) translation.
In fullscreen mode, QZ_PrivateWarpCursor() does not translate the desired
position through QZ_PrivateGlobalToLocal() before passing it to the Core
Graphics system. However, QZ_GetMouseLocation() does call the reverse
QZ_PrivateLocalToGlobal() even in fullscreen mode. This asymmetry caused
problems each time the mouse was moved.

Wish list for the 1.3 development branch: http://bugzilla.libsdl.org/ * Add mousewheel events (new unified event architecture?) * DirectInput joystick support needs to be implemented * Be able to enumerate and select available audio and video drivers * Fullscreen video mode support for Mac OS X * Explicit vertical retrace wait (maybe separate from SDL_Flip?) * Shaped windows, windows without borders * Multiple windows, multiple display support * SDL_INIT_EVENTTHREAD on Windows and MacOS? * Add a timestamp to events * Add audio input API * Add hardware accelerated scaled blit * Add hardware accelerated alpha blits * Redesign blitting architecture to allow blit plugins In the jump from 1.2 to 1.3, we should change the SDL_Rect members to int and evaluate all the rest of the datatypes. This is the only place we should do it though, since the 1.2 series should not break binary compatibility in this way. Requests: * PCM and CDROM volume control (deprecated, but possible)
