This is a known problem that I'm still struggling with.  I fixed things
to (I thought) work consistently in both the isometric and non-isometric
cases, but somehow the frequent updates due to cursor animation causes
draws in the world map to be missed - it all works fine in survey mode.
This is my punishment for going around tcl/tk's back and drawing directly
on a window... This last case is probably easy to fix, but I'm just not
seeing what the code is doing wrong...
