Fixed bug 1542 - SDL_Touch should reserve tilt_x and tilt_y

Gerry JJ 2012-07-14 19:42:23 PDT
The SDL_Touch structure currently reserves fields for tablet tilt and rotation
(marked "for future use"), but a tablet stylus can tilt in both x and y
directions in addition to rotation around itself (or, put another way, it can
rotate in x, y and z). So, the struct should probably reserve fields for both
tilt_x and tilt_y, not just tilt.
