If a LCD panel has a non normal orientation (mounted upside-down or 90 degrees rotated) then the kernel will report touchscreen coordinates with the origin matching the native (e.g. upside down) coordinates of the panel. Since we transparently rotate the image on the panel to correct for the non normal panel-orientation, we must apply the same transform to input coordinates to keep the aligned. https://bugzilla.gnome.org/show_bug.cgi?id=782294
