4458f363e3 [ttx] Write out name table entries as Unicode when possible 
https://github.com/behdad/fonttools/issues/54

There's a new attribute named unicode that can choose whether the
text in the XML entry is to be interpretted as Unicode, or as the
target encoding.

24264cb7f8 [subset] Fix chaos handling to be more inclusive 
If a contextual lookup recurses twice on the same index, that index
most be marked chaotic for the second recursion.

Also, when a non-1-to-1 recursion happens, only mark glyph locations
after current to be chaotic, not everything.

I believe this fixes a bug that before we were not inclusive enough.
Now we might have introduced more false positives, but we are at least
correct.

22ffbba4b7 [subset] Further narrow down cur_glyphs in recursive contextuals 
Improves NotoNastaliqDraft closure_glyphs() time from 60s to 50s.

This was originally introduced in 1d4fa13b4.  I'm fairly confident
new code is correct.

c4d0400004 [subset] Speed up closure_glyphs() a bit 
Was taking nine minutes on NotoNastaliqUrdu font.
With these changes it takes only(1) one minute now.

More coming.

4c4c65fac0 [sfnt] fix WOFF checksum adjustment calculation 
Use 'origLength' and 'origChecksum', instead of 'length' and
'checksum', to calculate the checksum adjustment of WOFF.

0bf67b50bd [glyf] Implement optimal glyph outline packing; disabled by default 
Dynamic-Programming-based algorithm.  Previously we had a greedy
algorithm only.

Unfortunately the savings are truly negligible.  In the order of ~20
bytes for each of the Roboto faces, less so for Noto fonts.  Even on
a 20MB font, it produced less than 100 bytes saving compared to our
greedy packing.  Either I made a huge mistake, or this is so not worth
it.  Anyway, the code is there, but disabled.

4e616d2f7f Accept MS Symbol cmap tables as Unicode-compatible 
Apparently these days these tables are used to encode symbols in
PUA, so they are still Unicode-compatible...

This follows a similar change in fontconfig.

de66a6466c [subset] Add --desubroutinize 
This seems to both make the font smaller for small subsets, and works
around a bug in our CFF hint stripping logic.

So, if you are passing --no-hinting, do pass --desubroutinize.
