Action Items

   Vlad: mobile perf? (which action ?)

   kuettel: started, looks good for woff2. Need to capture and
   share.

   action-116?

   <trackbot> action-116 -- David Kuettel to Decoder performance
   analysis on mobile devices -- due 2016-04-06 -- OPEN

   <trackbot> [10]http://www.w3.org/Fonts/WG/track/actions/116

     [10] http://www.w3.org/Fonts/WG/track/actions/116

   Vlad: A visual explanation of overall time consumed (load,
   decompress, etc) would be nice to have

   (discussion of what data we want and how we might obtain it;
   item due date pushed out)

   action-172?

   <trackbot> action-172 -- Chris Lilley to Register font media
   types -- due 2016-04-30 -- OPEN

   <trackbot> [11]http://www.w3.org/Fonts/WG/track/actions/172

     [11] http://www.w3.org/Fonts/WG/track/actions/172

   Vlad: seems to be moving along nicely

   action-186?

   <trackbot> action-186 -- Roderick Sheeter to Try time (decode)
   and size for null glyf/loca xform vs regular vs woff1 -- due
   2016-03-16 -- OPEN

   <trackbot> [12]http://www.w3.org/Fonts/WG/track/actions/186

     [12] http://www.w3.org/Fonts/WG/track/actions/186

   Me: Have first draft but suspicious of one set of #'s, wnat to
   poke more before publishing

   action-199?

   <trackbot> action-199 -- Khaled Hosny Ghetas to Investigate how
   we actually verify at tests, particularly how we verify
   internal handling. -- due 2016-03-30 -- OPEN

   <trackbot> [13]http://www.w3.org/Fonts/WG/track/actions/199

   (no update, push date for now)

Test Suite

   mustRejectInvalidBase128

   mustNotRejectIncorrectTotalSize

   [14]https://www.w3.org/Fonts/WG/wiki/TestPlan20-UserAgent

     [14] https://www.w3.org/Fonts/WG/wiki/TestPlan20-UserAgent

   mustLoadFontCollection - test looks fine; might be worth adding
   a note that no UA actually supports at this time

   Vlad: might be good to discuss at TPAC

   mustNotRejectGlyfSizeMismatch

   [15]https://www.w3.org/Fonts/WG/wiki/TestPlan20-Decoder

     [15] https://www.w3.org/Fonts/WG/wiki/TestPlan20-Decoder

   mustReconstructLSBs

   mustLoadFontCollection

   - I read the test as meaning it would be OK to unshare the
   tables as long as the result was a valid collection. Maybe
   clarify that there should be no change in which tables are/are
   not shared?

   jfkthame: maybe that's OK specwise even if it's an inefficient
   implementation

   [16]https://www.w3.org/Fonts/WG/wiki/TestPlan20-Format

     [16] https://www.w3.org/Fonts/WG/wiki/TestPlan20-Format

   reservedFlagsMustBeZero

   transformFlagsMustBeSet

   I think there was discussion of how this would actually be
   verified. Maybe one simple way would be just by looking at the
   transformed length and flags? - it should have these X flags
   and be Y bytes smaller type of deal.

   (discussion of The Validator)

   [17]https://www.w3.org/Fonts/WG/wiki/TestPlan20-AuthoringTool

     [17] https://www.w3.org/Fonts/WG/wiki/TestPlan20-AuthoringTool

   mustCheckLSBAllGlyfTables, mustNotApplyLSBTransformForOTC

   Marked for attention but seem fine

   Vlad: because I snuck them in while you were not looking
   ... That leaves us with just implementation for tests )

In Your Face at ATypI

   Vlad: ATypI will be good for our group. TPAC will offer a
   chance to chat with other groups, such as with CSS about
   fragments and collections.
   ... and the wooorld of tomorrow
   ... js api for deeper access to fonts, subsets, loading, etc
   might be a fun area to explore.
   ... Further suggestions welcome, including going outside
   current charter

   behdad: maybe something about variations, css, better
   compressing them?

   kuettel: unicode-range issues might be fun to chat with css
   group about
   ... so are we definitely doing both? (atypi, tpac)

   vlad: strongly recommended
   ... last call
