/* NautilusScalableFont is a GtkObject that provdes a simple
* interface to Raph Levien's librsvg FreeType2 based anti aliased
* text rendering.
*
* Currently, only Type1 fonts are supported.
*
* Fonts are automatically queried and used if available. Right
* now this is fairly simple code which does not handle all the
* complexities of the hell that is unix fonts.
*
* In the Star Trek future, we will use gnome-print (gnome-font?).
* However, we will keep the interface to scalable font usage simple
* and hidden behind this interface.
