2018-07-18Improve image size validation in CPDF_ScaledRenderBuffer.Lei Zhang
In CPDF_ScaledRenderBuffer::Initialize(), use the existing CFX_DIBitmap::CalculatePitchAndSize() function to figure out the pitch and size. Unlike the existing code, CalculatePitchAndSize() does a better job of checking for integer overflows.

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.
