Fixed bug #642

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.
