THINGS TO DO

(These should be resolved before releasing the next version.)

Figure out why 800ms delay of autoscrolling doesn't work on right side
of map. (apparent delay seems to jump suddenly)

Fix drawing of cylinder areas when scrolling in parts with negative
coords.

Provide instructions on unpacking/installing the Windows version.

In Windows version, handle error displays prior to tcl/tk interface
setup without needing console.

In W98, make game exit without hanging the machine.
