Hate to be an open-source snob... Linux + xwd. About $0. I like:

xwd -frame | convert - mywidget.gif

So I get the frame too. Of course, sometimes you don't want the frame, e.g. in
printed manuals.

I thought it would be interesting to make up a huge "test widget" (or several)
which exercised many of the various placement/labeling/sizing issues endemic to
IDL. Screen shots from all relevant platforms could be compiled, and it could
server as a cross-platform widget look/feel reference for those without the
luxury of machines to try it on. I fear the inconsistencies we'd find.
