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.

On a mouse click after the end of a line (except for the last line) in an XFA text edit, the caret was moved to the beginning of the next line, as the position after the space was actually in the next line. This CL changes the behavior so that the caret is positioned before the space in this case. Note it's possible to click directly to that position by clicking on the beginning of the next line.
