+ The code below parses font configuration file ${WXDFB_FONTDIR}/FontsIndex.

+
+ The file is standard wxFileConfig file text file. Each toplevel group
+ specifies one font bundle, font's name is the name of group. Group's entries
+ look like this:
+
+ [Font Name]
+ # font files (at least one of them must be present):
+ Regular=RegularFaceFile.ttf
+ Italic=ItalicFaceFile.ttf
+ Bold=BoldFaceFile.ttf
+ BoldItalic=BoldItalicFaceFile.ttf
+ # optional tag indicating this font is fixed-with (default is false):
+ IsFixed=1
+
+ Additionally, there may be DefaultXXX entries at the toplevel for every
+ family XXX and a Default entry that is shortcut for setting all families'
+ default, their value is name of the default font:
+
+ # optional tags indicating the default font for given family:
+ DefaultDecorative=Font Name
+ DefaultRoman=Font Name
+ DefaultScript=Font Name
+ DefaultSwiss=Font Name
+ DefaultModern=Font Name
+ DefaultTeletype=Font Name
