Detailed Description

Generic pure virtual & device-independant font class.

This class replaces the previously defined GFontInfos class that was attached to a VGDevice. It declares the minimal set of necessary methods/attributes to use a font. Fonts can now be seen as independant objects to be created by the VGSystem and then associated when necessary to the VGDevice.
