2017-03-22Remove CFX_FixedBufGrowDan Sinclair
This Cl replaces the CFX_FixedBufGrow class with std::vector. Change-Id: I85c85b7a8de4794840b561e09841bb464cfa9dfe Reviewed-on: https://pdfium-review.googlesource.com/3138 Reviewed-by: Tom Sepez <tsepez@chromium.org> Commit-Queue: dsinclair <dsinclair@chromium.org>
2017-03-21Make CPVT_WordPlace more conformant with the prevailing idioms.Tom Sepez
Add relational operators to replace CmpWord(). Leave CmpLine() for the moment as it saves some work. Remove CmpSec() and just inline comparison of the one member. Invert IsExist() as IsEmpty(). There is a big philosophical discussion as to whether things that are empty exist. I say they do, but they're just empty. Rename Default() to Reset(). Default sounds like a noun. Add AdvanceSection() method and call as appropriate.
