2018-08-29Remove FPDFAPI_ prefix from internal cid/encoder functionsTom Sepez
These look too much like public/ FPDF functions otherwise and yet they are not exposed anywhere beyond core/fpdfapi. Disambiguate one method vs. top-level function usage as a result.

2018-08-10Consolidate const_casts<> in FXFT_Get_Name_Index()Tom Sepez
There's a missing const in a qualifier in the third party FT library header, so rather than casting on every invocation, consolidate these into our wrapper macro. This may be easier to remove should the API ever get corrected. Part of the war on const_cast<>.

2017-11-07Remove m_bFlagExact from CFX_SubstFontNicolas Pena
This CL removes the single use case from |m_bFlagExact|. This flag allows the PDF viewer to treat a substitute font with a matching name as if it was actually an embedded font, which is wrong. For all substitute fonts, it is important to follow the longer process of first obtaining the unicode from the charcode to then obtain the glyph in the substitute font that corresponds to that unicode.

This method duplicates the behaviour of the const [] operator and doesn't offer any additional safety. Folding them into one implementation. SetAt is retained, since implementing the non-const [] operator to replace SetAt has potential performance concerns. Specifically many non-obvious cases of reading an element using [] will cause a realloc & copy.
