[time-nuts] Lady Heather's Window, font size

I have found it difficult to find out from within a Windows program how big
or small a particular font is rendered. Windows has a function called
TextWidth (and TextHeight) that does not work correctly for all fonts. It
seems to be video card driver dependant too, as the same fonts look
different (and have different size) on different video cards.
I wrote a small VB program that you can use to find out if windows is lying
for a particular font.
It's at http://www.ko4bb.com/VB_Projects/TextWidth/TextWidth.exe
This programs sets the size of the colored background to what windows says
the font takes. You can see some fonts work well, and some don't. I have
found that most of the time, Windows returns a size greater than is actually
That can be useful if you use these functions by letting you choose fonts
