Provisional bidi and shaping support
Adds fully working bidirectional text and simple shaping support.
The following works:
- bidirectional text according to the Unicode Bidirectional Algorithm
- simple shaper for mirrored forms (brackets, etc.) according to
rule L4 of the Unicode Bidirectional Algorithm
- reordering into visual order with correct line wrapping
However, the implementation certainly needs efficiency improvements
(caching, less malloc'ing), a proper shaper (HarfBuzz) needs to be
hooked up and various bugs with karaoke and positioning need to be
fixed.
