Fixed bug #642

Gerry JJ 2008-11-09 02:11:49 PST The SDL_MouseMotionEvent struct has a field named "tilt" (currently marked "for future use"), for tablet stylus tilt information. However, one value is not enough for this, as tilt is two-dimensional. Reserving only one field for future use is no good when you're going to need two, so there should be two fields, tilt_x and tilt_y.
