The code below parses font configuration file ${WXDFB_FONTDIR}/FontsIndex.
By default, the directory is $prefix/share/wx/fonts, but can be ovewritten
by setting WXDFB_FONTDIR environment variable.
The code below looks up and parses font configuration files FontsIndex.
The files are looked up in directories specified in the WXDFB_FONTPATH
environment variable (separated with :, similarly to the PATH variable).
If the variable is not set, $prefix/share/wx/fonts directory is used.
All subdirectories of directories on the path are scanned for FontsIndex
files.
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:
