I have found and repaired an initialization bug in the default properties
for rectangles.  This fix is in today's CVS version of gadgets.h

This fixes a change in behaviour of the svg and canvas terminals (maybe others?)
triggered by the 2009-07-04 patch.  However, the symptom shown by these terminals
was that the border of the rectangles was drawn with width 0.  It is not clear
to me whether the problem shown by the windows terminal is due to the same
initialization failure, or to something else.  Please test and report.
