   ed: first, animation module. mainly extension o apply to svg
   ... any other aspects?
   ... talk of animation apis, is that ready for discussion

   smfr: dean not on the call but has been working on it
   ... please add to agenda

   ChrisL: maybe an implementation roundup for that spec

   smfr: also the interaction with smil-based animation, and timing
   issues, timebase, etc
   ... also requestAnimationFrame API

   have people seen the inria work on timesheets in js with html5 and


      [8] http://wam.inrialpes.fr/timesheets/

   ed: next is svg paint in css generated images

   ChrisL: tab you will be there?

   tab: yes

   ed: can you prepare a wiki page describing this, or a link to a
   proposal, for the meeting?

   tab: sure will send link later today ... wait 2 weeks ago. dean

   shepazu: saw that, good idea

   tab: wil ladd to spec after wd is published

   fantasai: its already copied to /TR so start editing the ED

   ed: next is filter effects, dino and i working on this. one thing is
   defining hit testng
   ... pointer events mostly
   ... also the enable-background possible deprecation
   ... will update spec to 1.1se before meeting, also some new things
   ... these topics came up before

   ChrisL: with feDisplace it makes a big difference and people will be

   shepazu: there was mention of an opacity filter for pointer events.
   some maths discussions but its interesting

   smfr: seems like we should talk about this at f2f

   ed: doug maybe we can collect info on a wiki page for that agenda

   shepazu: happy to write up a strawman spec text. not seen input from
   tantek on that
   ... it affects css3 ui

   <fantasai> [9]http://dev.w3.org/csswg/css3-ui/#pointer-events

      [9] http://dev.w3.org/csswg/css3-ui/#pointer-events

   ed: next topic is extending svg compositing to css

   <ed> [10]http://www.w3.org/TR/SVGCompositing/

     [10] http://www.w3.org/TR/SVGCompositing/

   tab: not sure on technical side but it seems readsonable. want to
   see how it would be used in css.
   ... not sure how its would be used in html/css

   <TabAtkins_> tab: It seems very sensitive to the order of elements
   in the DOM, which may be troublesome when used with HTML, but then
   it might be okay, based on use-cases.

   ed: ast item is fx transforms, which covers 2d transforms

   ChrisL: status of 3d transforms wrt that?

   smfr: vincent was asking for that. 3d tx is laid ontop of 2d so they
   need to be kept in sync
   ... reason we had sepeaate specs was that we assumed 2d would be
   implemented more quickly, which happened

   ChrisL: is the sync automatic or does it need work

   smfr: needs work
   ... 2d shoudl lay groundwork for 3d

   ed: so from that list, anything missing?

   ChrisL: 'restricted text' (CGM) replacement for SVG, is there
   something from css we can use there?

   <fantasai> CGM?

   smfr: maybe we can get a solution for single line cases. css is the
   place for it. multiline is complicated

   ChrisL: maybe copyfit from gcpm?

   <hober> fantasai:

     [11] http://en.wikipedia.org/wiki/Computer_Graphics_Metafile

   ChrisL: will write it up before the f2f

   ed: parameters is not on the list of topics. room for discussion

   smfr: is that svg specific?

   ed: that is the question
   ... css3 images has a way to reference parts of images

   tab: which we get from media fragments

   smfr: maybe talk about media fragments. can also select part of n
   html document. somene suggested an id to a fragment ....

   tab: background-image-frame
   ... ie9 has multiple viewbox id support

   shepazu: link?


     [12] http://www.w3.org/mid/3C4041FF83E1E04A986B6DC50F0178290C57D9@TK5EX14MBXC297.redmond.corp.microsoft.com


     [13] http://lists.w3.org/Archives/Public/www-style/2011Jul/0139.html

   ed: for svg params, other params as well as viewBox. not clear if
   its useful outside of svg

   tab: there is intereting overlap, like the elem function in css3

   <dbaron> is there any filter stuff that should be on the f2f agenda?

   dnaron, yes

   ed: in coming week, we wil settle the fx day agenda and get some
   writeups on thew wiki. send details to fx mail list or add it to the

   smfr: location of fx meeting?

   ChrisL: same as css, microsoft confirmed they would host

   ed: also to confirm the dte since that came up recenltly. tues 26
   ... any other topics? or end early

   shepazu: on params, we want ot be compatible with css and there were
   so many svg use cases so the syntax ... ebecauseoof thedifferent use
   cases, is there overlap.

   tab: so its acessed how do i use it as a css background

   shepazu: any url syntax so works anywhere
   ... passing in keyword parameters via the url
   ... we should talk about it but css is only affected indirectly
   ... what about passing parameters *to* css

   tab: ties into the variables spec. will be writing up that now. good
   to coordinate there

   shepazu: different use cases bt the more similarity in features the
   better. maybe a telcon about that

   tab: cool

   ed: any other business?
   ... so unless any urgent business next meeting is f2f
