SolarWin - daylight position map for Windows 3.1

Windows version by Kevin Kelley, <kelley@merlin.hood.edu>, based on a
PC version by Dave Katz, <dkatz@merit.edu>, based on an X11 version
by John Mackin, <john@cs.su.oz.AU>, based on a Suntools program
by John Walker, <kelvin@acad.uu.NET>.

This program is a clock that shows which portion of the Earth's surface is
illuminated by the Sun.  It displays the current time in both the local
time zone and UTC.  The map window can be moved and resized, and it's 
position saved in the win.ini file.  Left mouse button brings up a menu,
and holding the right button and moving the mouse repositions the window.
The time line can be hidden with a menu choice.

To set your time zone correctly, put the following in AUTOEXEC.BAT:
  set TZ=EST5EDT
The "5" is the number of hours west of UTC for the local time zone,
and "EST" and "EDT" are the strings to display for standard and daylight
time, respectively.  Alter for your own time zone as need be.  If you
don't set it, it will default to the Source of BSD Unix (PST8PDT).

Version 1.1 changes:
   - Fixed bug in constructor where map sometimes didn't initialize
      correctly.
