Like I think I said before, the problem is the goto and rectangle
selection drags are activated once you cross into another tile. This is
bad. Just moving a single pixel is enough to trigger a drag, if you are
unlucky. The code should check for a substancial drag delta in the x or y
axis (in pixels, say 10 or 15 pixels), *not* that a tile boundary was
crossed to trigger a drag start.
