2018-05-31Handle image mask continuous loading correctlyWei Li
When image mask doesn't need multi-steps to load, ContinueLoadMaskDIB() will return LoadState::kFail as result. For this case, the loading should continue as usual instead of aborting.

2018-05-30Exclude certain colorspace types for calculating transparency backdrop color.Lei Zhang
Per discussion for the "CS" entry in the PDF 1.7 spec table 7.13, several types of colorspaces do not meet the requirements of this particular colorspace entry. In terms of implementation, this avoids hitting a NOTREACHED() in CPDF_PatternCS::GetRGB().

2018-05-30Make CPDF_Document cache CPDF_PagesTom Sepez
We cache pages not by page number, which can bounce around as pages are inserted or removed, but by page dictionary's object number. Since the page may be created under one function and used under another, we can't take the shortcut of not instantiating a render cache nor not parsing the page.

2018-05-28Revert 'Remove almost all usages of CFX_FixedBufGrow with std::vector'chromium/3444Nicolas Pena
This is a manual revert of the CL at: https://pdfium-review.googlesource.com/c/pdfium/+/32159 The only file manually changed was cpdf_renderstatus.cpp Reason for revert: the bug below shows that sometimes the vector size used is larger than the parameter given to CFX_FixedBufGrow. Thus, we will revert, then add vectors using std::max unless it's clear from the code that the code will never access indices outside.
