2018-05-18Fix issues with XFA font loadingRyan Harrison
This fixes two partially interrelated bugs with font loading in XFA documents. First, it adds falling back to the builtin fonts if there are no viable embedded or installed font for the top-level XFA font manager. Additionally it changes the load font code path in CXFA_FWLTheme to use the top level XFA font manager, instead of the one that just handles the system installed fonts. The main visible issue that this patch fixes is that currently using --font-dir with pdfium_test on a XFA PDF can cause text to not be displayed in widgets and/or NOTREACHED asserts. This occurs if there isn't a needed fonts embedded in the document or in the font directory, since currently PDFium will not correctly fall back to the builtins.
