The following applet demonstrates that under win95, the metrics
associated with the "Dialog 12" font don't match the displayed font.
The code displays a string in each of the supported fonts at several
point sizes. It uses the metrics to compute the string length in pixels and
uses the result to place the following string and a vertical line marking
the perceived end of the string. When run under Solaris, it formats
reasonably (though some of the selected fonts are pretty ugly :-). Under
win95, there is a noticeable problem in the formatting of Dialog 12.

This problem was originally reported by Applix, who has been having problems
laying out dialogs boxes because of the discrepancy. --bruce
