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.

2018-04-25Allow failing to build CFXA_FWLTheme if unable to load fontsRyan Harrison
The current implementation of this class potentially does a lot of work in the constructor. Specifically when getting a calendar font it might cause the whole font loading pipeline to run. This can fail if it is unable to load fonts. Breaking out the font loading part, so that the factory method can return nullptr if it fails. Additionally adding a guard for the case the font manager fails to load, which is the root cause of the crash in the bug.

Currently, one gets data from CPDF_PatternCS via its parent class's GetRGB(const float* pBuf) method. To squeeze through this interface, the caller has to pass in a float*, and CPDF_PatternCS::GetRGB() has to cast it to PatternValue*. Instead of doing casting, add a specialized GetPatternRGB() method to CPDF_PatternCS. In its parent class, CPDF_ColorSpace, add AsPatternCS() so callers can get a CPDF_PatternCS* from a CPDF_ColorSpace*. Change existing callers to use these new methods.

2018-04-19Fix caret moving to start of edit on click after the text.Henrique Nakashima

This is a known issue to be addressed later.
