:D
TTC Spec Changes
Vlad: indexes are easier to screw up than offsets, have to be
careful here
(discussion of offsets and indices)
Tl;dr Need to clarify what encoder and decoder should do wrt
table directory ordering and CollectionFontEntry indexes,
potential for confusion
Vlad: we should have a separate section with more detail on how
this is encoded, and the decoder will fall out of that
Data type for table directory indices could be 255UInt16
instead of UInt16; saves N_fonts *N_table_entries bytes in most
cases (50% of those bytes)
(agreed)
Everyone: review TTC spec, suggest tweaks/improvements
Vlad: Tests for TTC require spec to be nailed down
CTS
I fear we have disconnected ourselves; one moment :D
Khaled confirmed working on CTS
DK: Would we like to try to have Khaled join calls? (if
schedule works)
Vlad: Yes, particularly as we get more into CTS details. He is
confirmed as an invited expert.
Rod: Will ping Khaled
action to rsheeter Invite Khaled to attend conference calls

How TTC Actually Works
(discussion of how some of spec is a bit gray, can we get more
information of how it is used in the wild)
Last Call for Topics
DK: Mark Adler has started review of the Brotli spec
... He will be writing a decoder from scratch, based purely on
the spec, in github. Will provide link later, provided no
objections surface.
