2014-12-23XFA: merge patch from CL 731673003, fix incorrect operatorBruce Dawson
Fixing operator so that bCheckRight isn't always true. Unknown effect! VC++'s /analyze points out that this expression: FX_BOOL bCheckRight = type != 'D' || type != 'W';" is always true. This means that the tests for the right edge of a word Original patch from Bruce Dawson(brucedawson@chromium.org) BUG=427616 TBR=jun_fang@foxitsoftware.com Review URL: https://codereview.chromium.org/822763003
2014-12-23XFA: merge patch from CL 727083002, zero local variables.Bruce Dawson
Zero initialize ch to avoid possible bug - conditions are very subtle. Whether ch and iRet are read without being initialized depends on complex preconditions and cannot be determined by looking at these function. Therefore it seems prudent to zero initialize them to avoid any risk.

2014-12-19XFA: merge patch from CL 815103002Bo Xu
Update freetype to 2.5.4. Put freetype into third_party directory, cleaning up header files. Previously freetype header files are in core/src/fxge/freetype and core/include/thirdparties. There were also multiple fx_freetype.h. This patch removes the additional Foxit wrapper to make further update easier. Notice, for original freetype source code, the following files are modified and need to be updated accordingly in future update: third_party/freetype/include/config/ftmodule.h third_party/freetype/include/config/ftoption.h BUG=407341 R=thestig@chromium.org Review URL: https://codereview.chromium.org/815103002

Add a small LRU cache for the JBIG2 symbol dictionary. This reduces rendering time on my test document by over 10 seconds. It is super common for a JBIG2 dictionary to span multiple pages, so we don't want to decode the same dictionary over and over again.

2014-12-19XFA: merge patch from CL 441988Bruce Dawson
Avoid duplicate definitions of JSCONST_n*Hash and QeTable variables. QeTable is a 752 byte array that was defined in a header file. This caused it to be instantiated by the VC++ compiler 12 times, wasting 8,272 bytes of space in the data segment. Because 'const' implies 'static' this did not cause any duplicate symbol errors. JSCONST_n*HASH are a set of eight variables that are defined in a header file. This causes them to be replicated 15 times. The variables themselves are tiny but they are dynamically initialized and this dynamic initialization code is replicated 15 times. When tested on pdfium_test.exe the effect of this change is to: Reduce the .text (code) segment by 3,616 bytes. Reduce the .rdata section by 8,656 bytes. Reduce the total binary file size by 13312 bytes. These are the worst offenders for pdf.dll as shown in: https://drive.google.com/open?id=1BvubxoA2SU_2e4T5cq7jHTjc1TlT0qOndpIfX3DMeA8&authuser=0 This will also drastically simplify the list of work to be done for bug 441899 (getting rid of initializers).

Fix blank page issues caused by too strict check Before this fix, PDF parser aborts the parsering process when detecting an error. For this case, PDF parser just gives up parsering when it detects that the length of image stream is incorrect. The solution to this case is to find the tag "endstream" and "endobj" to calculate the length rather than aborting the parsering process.
