2018-05-01Add struct CJBig2_GRDProc::ProgressiveArithDecodeState.Lei Zhang
Track the decode state in one data structure. Also grab pointers to data structure members before tight loops when decoding. It turns out referring to this->foo in tight loops can actually slow down decoding.

Should FPDFDocumentFromCPDFDocument() be called several times under XFA, we may WrapUnique() the document several times. So cache a pointer back from CPDF_Document to CPDFXFA_Context to avoid this. Because of layering, introduce a placeholder type CPDF_Document::Extension. This is actually the first step in some larger XFA ownership cleanup, but makes a nice standalone CL around the one particular issue.

2018-04-25Don't store CE (comment extension) block data when decoding GIFRyan Harrison
GIF extensions are laid out as follows: <size byte> <chunk of data> <size byte> <chunk of data> ... <terminator byte>. The decoder needs to scan along the data, finding the size bytes to determine where the block ends in the stream, even if we don't care about the content. Currently the decoder is storing all of the data chunks, which are never used and take a lot of time to concat together if they are very small. Our implementation of the GIF spec does not handle this extension, so when scanning for the end of the block, just don't bother storing data from it.

This requires a little more caution before we decide that we have the CJS_Runtime, and not the CJS_RuntimeStub in a few casts. Adds a kDisableJavaScript option to the form fill embeddertests. Adds a --disable-javascript flag to the pdfium_test executable. Also adds a --disable-xfa flag while we're at it.
