Fixed bug #719 Mike Blaguszewski 2009-03-23 13:32:22 PDT Patch to 1.2 HEAD that fixes the issue Fixes bug in SDL 1.2.13 where clicking on an app's title bar to activate the app, when cursor capturing is enabled, will cause the window to jump. This is because SDL's handler for activate events calls a low-level Quartz function to move the cursor. Calling this when the mouse is down in the title bar confuses the WindowServer into thinking the title bar has been dragged. The patch defers processing of activate events in this case. The bottom line is that CGWarpMouseCursorPosition() is not safe to call when the mouse in down in a window's title bar.
