Subject: Debugged smooth walking except for 1 bug.

Adjusting to the edge is done such that it respects slight sideways movements of the dragon.
Fixed rounding issues in the whole game.  Improved debug messages.  Made sure that the dragon
does not turn like crazy around when clicking on the same pixel: the final point is always the
clicked one although the middle points made by shifted to make the animations smooth, and
preserve the dragons direction if he has not walked.

There is a bug with running turning animations as they seem to disappear for 1 frame and have
incorrect Z coordinate.  Will investigate it next.
