Add API to create a text object using a loaded font.
There is already a method to add text from standard font, this CL adds an option to add text using a loaded font. The font set into a text object is ref counted and may be released, so call LoadFont on this new text obj, and add a method to close the font. This CL also improves the SetText method so that it now uses a WideString, in preparation for CID fonts with non-Latin characters.
