. gr2fonttest --alltrace added
. Format 14 table support
. Not done. To be handled entirely in the compiler
. Bidi support for Unicode 6.3 Isolating direction controls

. Clang ASAN build support added for testing.
. Handle out of memory sanely.
. Documentation improvements
. Bug fixes:
. Enforce fonts having to store glyph attributes by monotonically increasing attribute number
. zeropadding was not getting called on feature tags
