/*
* Limits:
*
* Fontnames - A maximum of MAX_FONTS (32767) fontnames will be retrieved
* from X Windows with XListFonts(). Any more are ignored.
* I think this limit may have been set because of a limit in
* GtkList. It could possibly be increased since we are using
* GtkClists now, but I'd be surprised if it was reached.
* Field length - XLFD_MAX_FIELD_LEN is the maximum length that any field of a
* fontname can be for it to be considered valid. Others are
* ignored.
* Properties - Maximum of 65535 choices for each font property - guint16's
* are used as indices, e.g. in the FontInfo struct.
* Combinations - Maximum of 65535 combinations of properties for each font
* family - a guint16 is used in the FontInfo struct.
* Font size - Minimum font size of 2 pixels/points, since trying to load
* some fonts with a size of 1 can cause X to hang.
* (e.g. the Misc Fixed fonts).
*/
/*
* Possible Improvements:
*
* Font Styles - could sort the styles into a reasonable order - regular
* first, then bold, bold italic etc.
*
* I18N - the default preview text is not useful for international
* fonts. Maybe the first few characters of the font could be
* displayed instead.
* - fontsets? should these be handled by the font dialog?
*/

* Debugging: compile with -DFONTSEL_DEBUG for lots of debugging output.
