Revert 'Remove almost all usages of CFX_FixedBufGrow with std::vector'chromium/3444
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. Bug: chromium:847247 Change-Id: Iee54af023c8564824418a7d34a6385b0bc418ff0 Reviewed-on: https://pdfium-review.googlesource.com/33050 Reviewed-by: dsinclair <dsinclair@chromium.org> Commit-Queue: Nicolás Peña Moreno <npm@chromium.org>
