<krit> ed: If no one joins, I will scribe today. It is so much easier to just scribe yourself :P

<scribe> scribeNick: ed

FXTF meetings

DS: brought it up in CSS WG
... will bring it up on the mailinglist too
... not sure when the old telcon time was, but may not work for brian e.g
... was same time as SVG WG telcon but on mondays

ED: for me it's mostly a concern about participation and that there are workitems to discuss

DS: concerns these specs: blending&composition, masks, filter effects, transforms

ED: weekly telcon? bi-weekly? or based on agenda requests?

DS: just one meeting soon, then based on request is fine with me
... who would call in from SVGWG?

nikos: i'd call in

TB: me too

ED: probably me too

diffusion curves

Rik: needs more research

DS: as I understand it the diffusion curves can do some things meshes can't

nikos: right, DC are easier to author

rik: are they paint servers? how does it fit in?

CC: you could think of DC as a representation of what flash has

rik: no, flash doesn't have DC

CC: no, I meant the colors on the side of the curve
... for SWF
... more like gradients than fill or stroke

DS: if you have a path that crosses itself, does the path gets flattened first?

CC: it doesn't matter if you flatten it before or after

rik: meshes have the same issues, they're also not fill or stroke

DS: that means we either have DC or meshes, or both?

CC: gradient meshes are things of today, DC is still at the research states, think they will solve differnt usecases

TB: meshes are used in PDF, postscript etc, so useful to have
... is there a software package to play with DC somewhere?

CC: yes, the MS tool i posted to the mailinglist has a tool where you can play with DCs

TB: thinking of this from an artists standpoint

CC: yes, you have tools that take an image and trace it, you can also create from scratch

DS: do we want to resolve to not add DC to SVG2? and postpone it?

TB: if we want to put it in, someone has to sign up to do the work

CC: we don't need to say anything, if someone makes a proposal for it we can consider it then

(all agree)

extrapolated linejoin

TB: would like to call it 'talon'

<Tav> talon

doug: where are you getting that term?

TB: because it looks like a bird claw
... more unique than arc
... or extrapolated join
... because it describes the shape
... all the other shapes have five letters, this one is also five

CC: I don't know if talon is a good word, misleading in french

nikos: waht does it mean in french?

CC: the heel of a foot
... anyway, don't have a strong opinion on naming

ED: for me I think arc is more natural

TB: ok

Doug: take this to mailinglist

content model for svg2

DS: do we want the svg spec to say what the content model for elements is, or do we want to remove it from the spec?
... we dont' provide a DTD for SVG2 at the moment

doug: was talking to mike smith and robin berjon about producing an RNG for SVG2
... DTDs can't express SVG very well

DS: browsers don't validate, is that just a waste of time?

doug: validators validate
... for ppl being able to validate svg

DS: can a rect have a rect child, do we allow or disallow?

doug: we talked before about having a fallback model, where if something wasn't supported it would...
... so that you could fallback to another element

DS: so any arbitrary element would get treated as a <g> element
... is it transformable, locatable, editable?

doug: i reckon it would be treated just like a <g>
... all behaviours as if the arbitary element was a <g>

DS: but we have elements that are not transformable for example, so why should we assume the new element is transformable?

doug: haven't thought deeply about that

DS: who's working on this content model?

doug: I don't know anybody is

DS: seems like a huge gap in the spec
... what happens with elements that occur where they shouldn't be and so on

ED: we should define the model, at minimal describe what happens. it sounds as if you're asking for someone to step up and do the RNG?

DS: not sure if it needs to be an RNG, but we don't describe what should happen (yet)

ED: think we should get the model proposals up on the wiki or something, and then discuss at the f2f
... one easy way is to take the model already defined in SVG Tiny 1.2, and backport that, then if we want to change the model do it afterwards
... there was an RNG for 1.2Full but not sure what state it's in

DS: would someone take an action for backporting the content model wording from 1.2T?

<scribe> ACTION: ed to backport content model wording from 1.2T to SVG2 [recorded in http://www.w3.org/2012/11/15-svg-minutes.html#action01]

<trackbot> Created ACTION-3400 - Backport content model wording from 1.2T to SVG2 [on Erik Dahlström - due 2012-11-22].

next week is thanksgiving and some people won't call in, let's cancel next week's call

trackbot, end telcon
