Subject: Adds support for touchpad input.   By adding this, touchscreen input is also

supported.
The functionality is to use touchpad gestures instead of
pressing the arrow keys.   The mouse button must be pressed
for the gesture to be interpreted, so jumpy touchpads won't
affect play. by John Watlington wad@laptop.org
