Add CBDT support #73

Closed RoelN closed 4 years ago

RoelN commented 4 years ago

This PR will add support for CBDT fonts. It will produce a diff value in the same way as for vector fonts.

When using HTML output, an animated before/after GIF will be added per modified glyph:

The diff routine is optimised in speed and LOC, as comparing CBDT glyphs took a lot of time. This is the only change that also touches vector font diffs, but it produces the exact same diff value.
