2017-05-03SetPos to at most the file length to avoid overflowsNicolas Pena
This CL prevents arbitrary position setting which may cause integer overflows. In the bug in question, the PDF says the xrefs are located in a huge position. This then causes problems when calling CPDF_SyntaxParser methods.

2017-05-03Add a ToUnicode mapping when loading CID fontsNicolas Pena
This CL adds ToUnicode for CID fonts and adds a test to prove that using it works as intended. The test uses a Linux font for Japanese characters, and tests for other OS will be added in a followup. The ToUnicode works by defining the PDF charcodes as equal to the glyph indices and assuming that the freetype charcodes given by FXFT_Get_Next_Char are in fact the unicode values.

2017-05-02Add API to create a text object using a loaded font.Nicolas Pena
There is already a method to add text from standard font, this CL adds an option to add text using a loaded font. The font set into a text object is ref counted and may be released, so call LoadFont on this new text obj, and add a method to close the font. This CL also improves the SetText method so that it now uses a WideString, in preparation for CID fonts with non-Latin characters.
