Probably not the most elegant way, but the fonts of the following sample-document are now correcly created and displayed. example.pdf

I updated the base branch with another way to go about handling the FontDescriptor object. Kind of looks like the font was incorrectly encoded as type0 but I can't think of reliable way to handle this further up the in the Font Factory.
