One solution is to make it depend on the place you hit it, and
define the effect of a mouse movement as the projection onto the
tangent at that point.
So for example if you click on the bottom, moving left will rotate
clockwise, if you clock on the left side, moving up will do the same.
Top and right would to the inverse.
