+// CFontDesc Implementation
+/*! @class CFontDesc
+The CFontDesc class replaces the old font handling. You have now the possibilty to use whatever font you like
+as long as it is available on the system. You should cache your own CFontDesc as this speeds up drawing on some systems.
+
+\note New in 4.9: It's now possible to use custom fonts. Fonts must reside inside the Bundle/Package at PackageRoot/Resources/Fonts/.
