2017-09-27Make names of GIF types less opaqueRyan Harrison
A lot of the structs in the GIF code use acronyms that are non-obvious unless you are familar with the GIF spec, and even then lead to lots of looking back. Making the naming more explicit. Also converted GifImage to be a struct, since it didn't have any methods defined for it.

2017-09-27Enable PRINTF_FORMAT for clangDan Sinclair
This ports https://chromium-review.googlesource.com/c/chromium/src/+/599127 from Chromium to PDFium. Because VC++ does not have format-string checking for user-defined functions during normal compiles, because clang-cl had its format-string checking disabled, because some files are only compiled on Windows, and because VC++'s /analyze doesn't build all targets, and because VC++'s format-string checking is more lenient than clang's... 50 warnings about format-string mismatches crept in to Chromium's build. Seven of these were somewhat serious, with four being wchar_t*/char* mismatches because of base::FilePath and the other three being size_t/%d mismatches. Now that all of the mismatches are corrected this change enables PRINTF_FORMAT checking with clang-cl so that these bugs never return.

Previous implementation assumed that if the local colour palette was not specified and the global palette had its size specified, then use the global. If the global palette is disable, it will not have data, but it may have a size. Technically the size is giberish in this case, but the value is allowed to be non-zero, so isn't a sufficient check.

The core fix in this CL is a change to how LWZ decompression works, so that when the min code table size and the color palette size are different, color codes after the end of the defined color palette are considered errors. This CL also introduces a bunch of tweaks to the call return path, since there were multiple locations where the GIF decode failing status was being dropped on the floor, so the end widget would have a bitmap with the default colour in it, instead of nothing.
