The ToUnicode map should not be ignored when it exists. Doing so can cause a charcode to be assigned an incorrect glyph index, and will result in garbled text.

2017-04-12Some fixes to the fallback font code.Nicolas Pena
This CL applies several fixes to the fallback font code. - PDFium uses -1 to indicate that no glyph index was found, but freetype uses 0. In CPDF_TrueTypeFont, an index of 0 indicates a freetype failure, which means we should try to find the glyph from a fallback font. - Improve the fallback glyph calculation by going from original font charcode to unicode to fallback font charcode. - Consider the m_ExtGID on Mac when deciding the fallback.
