From: Alexandre Courbot
Subject: [SDL] Qtopia port fixes/improvments
-Whenever the screen is rotated, the pad is rotated as well,
-Fixed a mouse bug: when tapping on the screen, the click event was
often sent at the previous position of the stylus (resulting in strange
behavior in Scummvm for instance)
-Added the SDL_QT_INVERT_ROTATION environment variable which, when set,
rotates the screen (and the mouse, and the pad) the other way. This can
be useful for left-handed people.
