2018-06-13Make CJBig2_Context::GetHuffmanTable return constNicolas Pena
This CL changes GetHuffmanTable() to return a const pointer and fixes other members / functions accordingly.

2018-05-24Do some variable cleanup in CJBig2_ContextNicolas Pena
This CL cleans up variables in CJBig2_Context. It moves some declarations further, to when the variables are actually used. It also caches huffman tables in a vector of unique_ptr.

2018-05-14Merge some values of JBig2_ResultNicolas Pena
This CL merges some of the values of JBig2_Result. The only checks are against Success and EndOfFile || EndOfPage, so we only need three values: Success, EndReached, and Failure (for anything that does not match either of those two).

2018-05-09Use enum class instead of int in CJBig2_Contextchromium/3426Nicolas Pena
This CL changes CJBig2_Context return methods as follows: * Internal methods return JBig2_Result instead of int. * Public methods return a bool (for success/failure) instead of int. In a followup, several of the enum class values may be merged together since they are not all needed.
