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.

2018-05-25Make CPDF_Page retainable.Tom Sepez
Small step to reducing the differences between XFA and non-XFA. We still use the RetainPtr pretty much as if it were an unique_ptr, in that we're not yet caching pages and handing out multiple pointers to the same page in the non-XFA case. The one change is in page view cleanup, where we no longer need a boolean and can take (sufficient) page ownership with a RetainPtr. Tidy up some document.h -> page.h -> document.h circular inclusion while we're at it. NOTE: Wait for imminent branch to pass before landing. We'll want this to bake a while.

This is an obstacle to introducing dummy CPDF_Pages to underly all CPDFXFA_Pages, since we would then have a parserless CPDF_Page, whose parse could never succeed or fail. The m_ParseState would never change, and if the caller dutifully recalls us until that changes, we hang. Small separate CL since it might impact non-XFA cases unexpectedly.

Currently, one gets data from CPDF_PatternCS via its parent class's GetRGB(const float* pBuf) method. To squeeze through this interface, the caller has to pass in a float*, and CPDF_PatternCS::GetRGB() has to cast it to PatternValue*. Instead of doing casting, add a specialized GetPatternRGB() method to CPDF_PatternCS. In its parent class, CPDF_ColorSpace, add AsPatternCS() so callers can get a CPDF_PatternCS* from a CPDF_ColorSpace*. Change existing callers to use these new methods.
