Date: Sat, 31 Aug 2002 15:42:45 +0200 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.
