16:05:59 <Vlad> Topic: Discuss the scope of different approaches to IFT.
16:06:35 <Garret> Skef: much has changed over the last few months. Discussing the new proposals in light of judgments of the old proposal.
16:06:55 <Vlad> scribenick: Garret
16:06:56 <Garret> Skef: when discussing IFTB we mostly talk about it in the terms of CJK. but much has changed.
16:07:08 <Garret> Skef: I think we should unset assumptions about how things are used.
16:07:19 <Garret> Skef: we know for IFTB it won't provide much utility for shaping data.
16:07:37 <Garret> Skef: for any font that's biased towards glyph data as opposed to shaping there's good applications.
16:07:49 <Garret> Skef: that includes large LGC and maybe arabic.
16:08:26 <Garret> Skef: doesn't allow subsetting of axes, but the overall effect is it changes the proportion to the number of glyphs. So still useful if you don't subset axes.
16:09:36 <Vlad> Topic: Static IFT presentation and demo
16:09:40 <Garret> https://docs.google.com/presentation/d/1t0Wrng4F1a_rNQNf7li4j3L4XQ2sIKaBQFFH-5HISDY/edit?usp=sharing&resourcekey=0-XmhRsNCC9HZRTXLKEf8dxg
16:09:44 <skef> The following are notes on Garret's presentation on static IFT that are not part of the slides, which will be shared separately
16:13:16 <skef> Slide "Solution" clarification: Static subset patches are ordered, and cannot be applied independently. One can speculate about other options
16:14:30 <skef> Order-independent patches likely implies semantic patches (patches that take the format into account)

16:31:28 <skef> Slide "Patch Encodings": Garret and Skef will discuss deeper mixing between IFTB and static patches offline
16:53:23 <skef> Even dynamic patches will become more coarse-grained with this change (driven by contents of the IFT table)
16:56:13 <skef> Important to underline: The dynamic subsetting protocol is changing significantly under this proposal.
17:00:47 <skef> Skef: The number of levels of the graph included in a given subset should be configurable
17:01:23 <skef> Garret will experiment with being able to encode multiple levels
17:04:33 <skef> We anticipate switching to table-based brotli patches. This will require some explicit specification. There is already some table-related code in the IFTB client
17:05:38 <skef> We should revisit the question of whether table checksums can be optional
17:09:40 <skef> We can also add language to the spec indicating that you only need to rebuild an "snft" format font on the client side if you need it -- you might instead just keep tables separate
