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.

2017-04-07Remove the ICC transform where it is never initialized.Nicolas Pena
- All callers of CFX_DIBitmap methods use nullptr as the ICC Transform. - The CFX_ScanlineCompositor is always initialized with a null ICC transform. Many of its methods call TranslateScanline from the ICC module. This method casts just uses ((CLcmsCmm*)pTransform)->m_hTransform, and this should not be done when pTransform is nullptr.
