mapster v0.1 -- known bugs and limitations as of June 14, 1998

* polygon_cancel_point deletes all lines drawn, up to the time it is
invoked, although the correct points are retained in memory and the
polygon can still be completed

* image placement and window resizing are a little bit screwy

* the dialog for entering area names doesn't always stay on top

* when you save the output, it brain-deadly overwrites any existing
file with the same name -- no option to change the name or relocate
the file

* need a mechanism to prevent objects from overlapping or going off
the edges of the image. Also need to allow for drawing objects
directly adjoining each other.
