Thanks! It's been a lot of fun working on it in my spare time lately. I'm
glad that a few people have found it worthwhile.

I've dug around in the code to try and figure out what is going on here and
I think I understand the problem now. I'm no expert on fonts, however.
The editor component I am using is trying very hard to maintain a perfect
grid of character cells where the Nth character on line X+1 is directly
below the Nth character on line X. In order to do this it checks the
character width of the font in normal, italic, and bold styles. If the
syntax highlighter indicates to the editor that it might bold some of the
characters in the edit window then the editor will draw all characters at
the bold-style character advance value. The code uses GetCharABCWidths to
determine the character width to use for TrueType fonts. For raster fonts
it uses tmAveCharWidth.
The bottom line seems to be that if you use raster fonts with my revised
RcxCC the text will be drawn in bold-style character widths (with the
default syntax highlighting settings). If you want to use your font and
have it draw the characters in normal-style character widths you'll have to
not use the bold style in any of the Color settings in the Preferences
dialog. The default is to bold the Keywords. You might consider removing
the bold attribute and choosing an alternate color for Keywords. I've also
noticed some less-than-desireable behavior with italicized text while using
your font. It seems that drawing italicized text when using non-TrueType
fonts will clip the last character on a line. Modifying this behavior is
definitely not a high priority.
Thanks,
John Hansen
