Description

Class PDTrueTypeFont assumes that there is always a non-null FontDescriptor(Dictionary) available. However, I've seen this assumption failing with a NullPointerException in method PDTrueTypeFont#drawString when trying to render PDF documents that make use of external TrueType fonts.

I've implemented a small patch that initializes empty FontDescriptorDictionary if one is missing, and tries to fill it in with information available from the external TTF resource.
