Add support to specify TTF font file for all text representations.
It is now possible display 2D/3D text with user provided TrueType font files,
and thus use different fonts than the built-in ones (Arial, Courier & Times).
This feature is accessible by choosing FontFile
as font family in the GUI
and then specify the full path to the .ttf
file in the font file path field.
