This fixes the previous bugfix, which causes that I could not re-run the same
program (e.g., by repeatedly clicking on the hollow tree) if the hero did not
move at least one pixel.

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.

The hero does not walk yet (it still teleports to the target immediately),
but that is just because the actual walking algorithm is left trivial first.
However, the main game loop, callbacks, and waiting all already work with
the general framework.

The current algorithm is much better than the original player'ss one and it
find really nice curved paths.
Also, started preparing interface for actually walking along this path.
svn-id: r45622
In particular, breadth-first search algorithm for getting the shortest path
in the walkable area and an algorithm making the path oblique when possible.
svn-id: r45591
Also, fix a bug when loading the default walking map (wasn't implemented)
and setting font size. The reason I move this code into a new module is
because I will augment it with other walking-related algorithms soon.
