  Notes:

  - Interpretation of the hints:

      0                    No preference for pitch
      FXFont::Mono         If specified, match for fixed pitch fonts are strongly preferred
      FXFont::Variable     If specified, match for variable pitch font strongly preferred
      FXFont::Dual         If specified, match for dual pitch font strongly preferred

      0                    No hints given
      FXFont::Decorative   Ye Olde Fonte
      FXFont::Modern       Monospace fonts such as courier and so on
      FXFont::Roman        Serif font such as times
      FXFont::Script       Cursive font/script
      FXFont::Swiss        Sans serif font such as swiss, helvetica, arial
      FXFont::System       Raster based fonts, typically monospaced

      FXFont::X11          Force X11 raw font specification

      FXFont::Scalable     Strong emphasis on scalable fonts; under Windows, this means
                           TrueType fonts are desired

      FXFont::Polymorphic  Strong emphasis on polymorphic fonts; under Windows, this means
                           TrueType fonts desired also

  - FONTENCODING_DEFAULT means we prefer the fonts for the current locale;
    currently, this is hardwired to iso8859-1 until we have some means of
    determining the preferred encoding from the locale.

  - FXFont::Italic is a cursive typeface for some fonts; FXFont::Oblique is the same
    basic font written at an angle; for many fonts, FXFont::Italic and FXFont::Oblique
    means pretty much the same thing.  When matching, FXFont::Italic and FXFont::Oblique
    are considered closer to each other than FXFont::Straight.

  - A weight value of 0 indicates preference for non-bold font.

  - XFontStruct.ascent+XFontStruct.descent is the height of the font, as far as line
    spacing goes.  XFontStruct.max_bounds.ascent+XFontStruct.max_bounds.descent is
    larger, as some characters can apparently extend beyond ascent or descent!!

  - Registry section FONTSUBSTITUTIONS can be used to map typeface names to platform
    specific typeface names:

        [FONTSUBSTITUTIONS]
        arial = helvetica
        swiss = helvetica

    This allows you to change fonts in programs with hard-wired fonts.

  - Text txfm matrix [a b c d] premultiplies.

  - Should we perhaps build our own tables of font metrics? This might make
    things simpler for the advanced stuff, and be conceivably a lot faster
    under MS-Windows [no need to SelectObject() all the time just to get some
    info; also, this could be useful in case the drawing surface is not a
    window].

  - FOR THE MOMENT we're creating a dummy DC to keep the font locked into the GDI
    for MUCH quicker access to text metrics.  Soon however we want to just build
    our own font metrics tables and determine the metrics entirely with client-side
    code.  This will [predictably] be the fastest possible method as it will not
    involve context switches...

  - Matching algorithm slightly favors bitmapped fonts over scalable ones [as the
    latter may not be optimized easthetically; also, the matching algorithm should
    not weight resolution as much.

  - UNICODE means registry and encoding are set to iso10646-1

  - More human-readable font strings (e.g. registry):

       family [foundry],size,weight,slant,setwidth,encoding,hints

    For example:

       times [urw],120,bold,i,normal,iso8859-1,0

    Note that the size is in decipoints!

  - Get encoding from locale (see X11).
