Fixed bug #898 Jeremiah Morris 2009-12-09 16:07:17 PST 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.

11 Blit the \fBoverlay\fR to the surface specified when it was \fIcreated\fR\&. The \fI\fBSDL_Rect\fR\fR structure, \fBdstrect\fR, specifies the position and size of the destination\&. If the \fBdstrect\fR is a larger or smaller than the overlay then the overlay will be scaled, this is optimized for 2x scaling\&.
