2017-04-26Guard against overflow in CFX_BilinearMatrix code.Dan Sinclair
If any of the values in the matrix used to initialize the CFX_BilinearMatrix are close to INT_MAX then the numbers can overflow when multipled causing undefined behaviour. This Cl uses a pdfium::CheckedNumeric to handle the multiplications and then assigns back to the int value if valid.

2017-04-17Fix buffer management issues in CFX_SAXReader.Tom Sepez
Re-write to use std::vectors rather than self-managed buffers. Includes test case that breaks before patch. Formerly, we had two independent buffers whose position were tracked by the same variable, assuming that only one was being written to at a given time. This is a bad idea because it's easy to forget to zero the index when switching buffers, and start indexing into one using previously computed offsets from the other. Additionally, there were cases where the location of a partial entity wasn't discarded when switching states thus clearing the buffer tracking said entity.
