2018-08-13M69: Fix a JBIG2 decoding regression.chromium/3497Lei Zhang
When trying to sanity check SBNUMINSTANCES for JBIG2 text regions for https://crbug.com/837192, the check did not take data encoding into account. Fix this by assuming there is a potential for 16:1 compression in the lossless encoding.

2018-08-07Merge to M69: Bounds check lineSrc in JBig2_Image.cpp.Tom Sepez
No matter how the dimensions might be determined, we know the hard end of the source line, and can use it for a bounds check. We expect the size is quantized to a multiple of m_stride, so as long as each block operates within an m_stride, the initial check should be sufficient.

2018-07-16Process data changes regardless if they can be formattedRyan Harrison
UI elements in XFA can have two different <picture> clauses with different meanings. One is a formatting statement that dictates the format the underlying data should appear in. The other <picture> occurs within an <validate> block and specificies what format the underlying should be. If it doesn't fit this <picture> the <validate> block indicates what should occur. In the existing code actually running the second <picture> type was being conditionally guarded on whether of not the formatting of the first type succeeded. This CL moves the calls related to data changing earlier, to before the formatting and UI updating occurs.
