2018-07-11Do not store cross ref v5 obj within document.Artem Strygin
Currently, not necessary to store the cross ref v5 obj within CPDF_IndirectObjectHolder(CPDF_Document), because all necessary data from the cross ref are parsed or cloned, and owned by CPDF_Parser seperately from CPDF_IndirectObjectHolder. Also this fix regression from commit 4ea4459e.

2018-07-06Make MarkData::mMarks a vector of RetainPtr<CPDF_ContentMarkItem>Henrique Nakashima
It is currently a vector of CPDF_ContentMarkItem. Copying MarkData whenever a content mark is opened or closed is inefficient since each MarkData will have copies of the same CPDF_ContentMarkItems. This CL changes the vector inside MarkData to contains only pointers to the CPDF_ContentMarkItems rather than copies of those items. More importantly, this unifies the dictionaries of each content mark. Previously, there were as many copies of those dictionaries as content marks scope changes inside the mark with parameters.
