From: David Hedbor
Subject: Qtopia patches (input grabbing and iconify)
Ok, here's a patch that adds support for SDL_WM_GrabInput (default
state is "ungrabbed") and SDL_WM_IconifyWindow. Also has some other
tweaks such as taking additional steps to clean up when exiting
(bypassing certain bugs in some versions of Qtopia and/or OPIE) and it
also maps Key_F33 to Key_Return (this is the Zaurus 'ok' key).
