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.

To compile and install SDL: 1. Run './configure; make; make install' If you are compiling for Windows using gcc, read the FAQ at: http://www.libsdl.org/faq.php?action=listentries&category=4#42 If you are compiling using Visual C++ on Win32, you should read the file VisualC.html 2. Look at the example programs in ./test, and check out the HTML documentation in ./docs to see how to use the SDL library. 3. Join the SDL developer mailing list by sending E-mail to sdl-request@libsdl.org and put "subscribe" in the subject of the message. Or alternatively you can use the web interface: http://www.libsdl.org/mailing-list.php That's it! Sam Lantinga <slouken@libsdl.org>
