/* This is needed since some windows registry names don't match

* - The registry advertises that the file david.ttf contains a
* font with the full name "David Regular" when in fact its
* just "David".
* Directly fix up these known cases as this is faster.
* If a font which doesn't match these known cases has no file,
* it may be a font that has been temporarily added to the known set
* or it may be an installed font with a missing registry entry.
* Installed fonts are those in the windows font directories.
* Make a best effort attempt to locate these.
* We obtain the list of TrueType fonts in these directories and
* filter out all the font files we already know about from the registry.
* What remains may be "bad" fonts, duplicate fonts, or perhaps the
* missing font(s) we are looking for.
* Open each of these files to find out.
