   Ken had commented "Adobe applications tend to prefer the
   horizontal advances in the CFF over those in the 'hmtx'
   table.", is that the comment you were referring to?

   <scribe> scribenick: rsheeter

Face to Face

   Where is it?!

   kuettel to tell us where

   <jfkthame> RSheeter: yes, that sounds like what i recall. and i
   checked, the spec at
   [10]https://www.microsoft.com/typography/otspec/hmtx.htm
   definitely says they should use hmtx widths

     [10] https://www.microsoft.com/typography/otspec/hmtx.htm

   That quote is from
   [11]https://lists.w3.org/Archives/Public/public-webfonts-wg/201
   5May/0038.html

     [11] https://lists.w3.org/Archives/Public/public-webfonts-wg/2015May/0038.html

   kuettel: perhaps we should have an agenda? And maybe we could
   get the compression team to come tell us the latest on woff2,
   brotli perf gainz, etc

   Vlad: You are out of order, QUITE out of order!
   ... (but it's ok)

   (I think me and jonathan are guilty too, having mixed in hmtx)

HMTX

   in particular, making it optional, as proposed in
   [12]https://lists.w3.org/Archives/Public/public-webfonts-wg/201
   5Oct/0009.html

     [12] https://lists.w3.org/Archives/Public/public-webfonts-wg/2015Oct/0009.html

   (basically we should allow null transform)

   (dissent fails to arise)

   jfkthame: Should we support a null transform (which would ahve
   to be 1) for glyf/loca

   kuettel: undoing the preproc may also be costly in time so for
   use cases where you decode many times it could be helpful

   we could gather size/time data for both options to better
   compare

   FYI we serve *only* woff2 to supporting Firefox versions;

     [13] https://twitter.com/googlefonts/status/634031795059556352

   (discussion of using 0 for glyf/loca null transform, which
   would break all existing files)

   Vlad: messy short-term but perhaps better long-term?
   ... null transform might also be useful to
   incremental/streaming fonts, as services like Typekit do

   jfkthame: We could even recommend "profiles" for usage
   (particularly as we get more transforms)

   (compact, fast, etc)

   Note also that if a caching client is doing the decode many
   times we could pay the decode fee (time) repeatedly

   action rsheeter Try time (decode) and size for null glyf/loca
   xform vs regular vs woff1

   <trackbot> Created ACTION-186 - Try time (decode) and size for
   null glyf/loca xform vs regular vs woff1 [on Roderick Sheeter -
   due 2015-10-14].

   Vlad: we agree to modify hmtx as suggested (0 is null transform
   and transform isn't mandated)

   action vlad Incorporate Jonathans hmtx suggestion into spec

   <trackbot> Created ACTION-187 - Incorporate jonathans hmtx
   suggestion into spec [on Vladimir Levantovsky - due
   2015-10-14].

Face to Face timing

   Vlad: to accomodate time zones for jfkthame and Zurich probably
   want to do compression update first thing

   kuettel: Maybe compression 11am Sao Paulo time to allow for
   logistics

   <kuettel>
   [14]http://www.timeanddate.com/worldclock/meetingtime.html?iso=
   20151013&p1=268&p2=233

     [14] http://www.timeanddate.com/worldclock/meetingtime.html?iso=20151013&p1=268&p2=233

   All: discussion of what time will work for all locations,
   leaning to 10:30 or 11:00 am sao paulo time for compression.
   kuettel to confirm.

   [15]http://www.timeanddate.com/worldclock/meetingtime.html?iso=
   20151013&p1=268&p2=233&p3=136

     [15] http://www.timeanddate.com/worldclock/meetingtime.html?iso=20151013&p1=268&p2=233&p3=136

   that's London, Zurich, and Sao Paulo

   Vlad: so we are planning compression update, test suite
   discussion, and planning for any future items. Also coffee.
