this class implements the font chooser.
Notice:
this is a very old dialog;
it was written before the UI-framework was available and the UI is completely
programmed manually (see initialize method).
Therefore, it desperately asks to be rewritten using the UIPainter...

#fontName
'Shows the full name of the selected font.'
#fontEncodingFilter
'Filter fonts by encodings.\Almost any can be used for Latin1 languages (English, German, French, Italian etc.).\For other European languages, it should be a Latin-X or Unicode font;\For most middle and far east languages, a Unicode font is required.\\Notice that although ISO10646 is Unicode, many fonts only contain a subset of the required characters.\Check the preview above.'
#fontsEncoding
'Shows the selected font''s encoding.'
#xftFontsOnlyHolder
'Filter to only show the nicer looking xft fonts and ignore the ugly X fonts (Linux/OSX only).\\Be aware that if X is used with remote windows via a slow communication line,\it may be preferrable to avoid xft fonts, as they require much more network bandwidth.'
#pixelPointSwitch
'Switch between point and pixels in the size list.\A point is defined as 1/72th of an inch, and a common unit in typesetting.\Not to confuse with pixels, which are dots on your screen.\It is usually not a good idea, to specify font sizes by pixels.'
#flushCachedListOfFonts
'Flush the cached list of fonts, and rescan the system for available fonts.\This may take a long time in some systems,\and is only needed if you install new fonts while ST/X is running.'
#changeInAllTextViews
'If checked, your font choice is applied to all text views (in ST/X),\and will also be the default for new windows.\Otherwise, it will only affect the current textview.\\To make your choice persistent across sessions, go to the settings dialog and save the settings into your preferences file.'
