cyril: can we have a link to the chapter where the edits were
made?

Tav: I don't remeber :)
cyril: found i
t
Tav: might be good to have a link
krit: Question, what styling on element definition?
heycam: have not tried the lrecently one
Tav: as a proposal, a table seems to be ok
... problems with table might be semantcis, but that is ok and
can be fixed later

... but there seems no trouble to switch to heycam proposal
without it
heycam: yes i think that is ok

heycam: you are aksing because of edits that you are doing?
krit: yes, I would like to have a style at the beginning
heycam: can be changed later easily

it can be discussed on the list
cyril: I reviewed marker and have a list of changes, send it
tomorrow to the list
Tav: everyone is interessted on it, so it might be better
cyril: I mean public list or wg list

heycam: unlikely
cyril: who else would come to paris?

krit: I just was not happy about the red color on elements
... continue with smaller and bold text for attributes and
elements
heycam: I am fine if there are solutions that make it better
... list of quted attribute or element list might look scarry
krit: do you have an example?
heycam: try to get an example?
<heycam>

click the "show" next to "presentation attributes"
[19] https://svgwg.org/svg2-draft/shapes.html#RectElement
krit: looks ok for me
... quotes are inside of links on attributes and elements, but
outside for properties
heycam: I try to change it and look how it looks liek
Tav: heycam: but it is good as it is
<heycam>
[20]https://svgwg.org/svg2-draft/pservers.html#MeshGradients
has an example of this note
[20] https://svgwg.org/svg2-draft/pservers.html#MeshGradients
krit: current style looks great, will we have the same style on
WD?
heycam: yes, with exception of background
... for WD, do we want to publish it without background colors?

ng
[21] https://svgwg.org/svg2-draft/text.html#TextOverflowProcessing
krit: I think so, yes
ed: that is fine for me
... yellow background should be reviewable text
krit: but do we want to have backgrounds on WD at all?
heycam: might be ok to have different styles for publishing WD
... we don't want to have annotations either
krit: property and attributes have different blueish colors
heycam: yes, planned
krit: what for presentation attributes, should they be the
attribute blue, or property blue?
heycam: they should have the attribute blue

https://svgwg.org/svg2-draft/attindex.html#PresentationAttributes
krit: at the moement spec is not talking about presentation
attr, but about the property, does this change for current
attributes that move to presentation attributes as well?
heycam: they might later, yes

should we remove glyph-orientation-{horizontal,vertical}?
Remove glyph orientation vertical and horrizontal
should we remove glyph-orientation-{horizontal,vertical}?
heycam: In CSS3 it will be a text orientation property
... it is not in gecko, but in opera and webkit
... is it ok to remove it yet?
... the current writing mode spec has some possibility to use
the SVG orientation property
... so should this spec still have that? is it necessary?
Tav: we might be the wrong people to ask
heycam: since CSS has it, do we need it in SVG? Do we want to
continue with CSS?
krit: does CSS has angles for text orientation?
heycam: might be limited
... but angle on SVG must be a multiple of 90deg

krit: upside down text is not possible for CSS
heycam: yes
... not sure about vertical text implementations
Tav: inkscape has it
krit: webkit as well
ed: opera has some support for it
heycam: Iam aslo happy to keep it in the spec

nikos: Is it already deprecated?
heycam: I think so
... maybe not
... if people are confortale enough we can remove it.
... or first deprecating?
Tav: I don't know
nikos: we need feedback from japan first
ed: doe we have an action for someone?
heycam: yes
<scribe> ACTION: heycam will look into how removing
GlyphOrientationHorizontalProperty would influence the web
[recorded in
[26]http://www.w3.org/2012/05/31-svg-minutes.html#action01]
<trackbot> Created ACTION-3299 - Will look into how removing
GlyphOrientationHorizontalProperty would influence the web [on
Cameron McCormack - due 2012-06-07].
Removing kerning property in favour for font-kerning

[27] http://lists.w3.org/Archives/Public/www-svg/2012May/0101.html
<heycam> letter-spacing
heycam: only webkit implements kerning
... it gives posibility to override kerning of font
... and turn off automatical kerning
... font-kerning can turn on and off automatic kenring\
... you could get all functionality of kerning with turn off
kerning with font-kerining and letter-spacing
... do we want to remove duplicated behavior?
ed: I think so
krit: the quetion is if authors can still rely on specs, if we
remove parts that are specified later.
heycam: if implementations haven't picked up things, we are in
a lucky position that we still can change behavior
ed: on the other hand kerning is more doing letter-spacing, so
it is not doing what it suposed to
heycam: I was able to find 5examples where kerning was used
krit: is it already deprecated?
heycam: it is not
krit: At least we can agree to deprecate it
heycam: as longer it remains on the spec, as more likely it
will be used
... my preference is to remove it
krit: I don't have a strong feeling
ed: any objections to remove it?
resolution: remove kerning from spec
... remove kerning property from SVG spec
Tav: we should note that it got removed and how to get the same
behavior?
heycam: good idea
<scribe> ACTION: heycam remove kerning and mention to use
font-kerning and letter-spacing instead [recorded in
[28]http://www.w3.org/2012/05/31-svg-minutes.html#action02]
<trackbot> Created ACTION-3300 - Remove kerning and mention to
use font-kerning and letter-spacing instead [on Cameron
McCormack - due 2012-06-07].
Should opacity property apply to markers
krit: does spec disallow it?
heycam: no
... question is from implementations point of view
krit: would be more interessting to have marker and stroke as
one piece
<ed> so this is talking about <marker
opacity="0.5">...</marker>, right?
heycam: I know what you mean, could be interessting
<heycam> ed, yes
Tav: we could use the new keywords
krit: that wouldn't solve the problem that you see that they
are not one piece
nikos: that is something the nec compositing spec can help
with, let me find a link
krit: the spec does allow opacity on markers, so you are asking
for disallowing it explicitly?
<nikos> if they're in a knock-out group it would solve the
problem of the stroke and the marker looking like different
objects

<nikos> section 8.3 I think you were referring to Cam
heycam: not really. Just wanted to discuss it, was not aware
that it is allowed at that point
nikos: was added by rik, and he propably want to work more on
it
heycam: looks like we can get the behavior that dirk wants
krit: well, we were asked about it on webkit
(talks about marker and stroke being one unit)
ed: sounds reasonable
<heycam> ISSUE: consider allowing stroke and markers to be
rendered as one unit wrt opacity
<trackbot> Created ISSUE-2443 - Consider allowing stroke and
markers to be rendered as one unit wrt opacity ; please
complete additional details at

<heycam> ISSUE-2443: Maybe the Compositing spec will allow
this.
<trackbot> ISSUE-2443 Consider allowing stroke and markers to
be rendered as one unit wrt opacity notes added
ed: next topic?
Meaning of overflow: auto for SVG elements
krit: is it about overflow-x/-y
heycam: related
... in CSS it means scrollbars if if affects a bigger region
... in SVG means the same as visible
... auto means in CSS never paint outside the bix, while in SVG
always outside the box
... proposal: change behavior to CSS described behavior
... the current behavior of gecko
ed: might cause more clipping and perf lost on SVG
heycam: auto is not the default value
ed: true, hm not sure
krit: I would agree heycam because of consitence with cSS spec
ed: I am not sure if the CSS definition even applies to SVG
since there's no scrolling in svg
heycam: For me it is more about scrolling
... in HTML content it will clip to the content
... no scrollbars
... so it is more like hidden invisible
... overflow: scroll means the same a overflow: hidden in SVG
ed: I think heycam arguments are good
<ed> I'd agree that auto is more similar to scroll, which in
svg is the same as hidden
heycam: anyone against changing defintion of overflow: auto
resolution: Accept the proposal of heycam to go the CSS way for
overflow: auto

overflow: auto [recorded in

[32] http://lists.w3.org/Archives/Public/www-svg/2012May/0094.html
heycam: should both apply the same way like for HTML
... don't see any reason why we shouldn't do that
krit: think it can be a benefit for authors
ed: it is not more confusing than having CSS Transforms on box
....
... what is the usecase in SVG?
krit: different clipping behvairo
heycam: how is it done on webkit?
krit: not fully sure

heycam: anyway, implementations are different now
krit: any conclusion?

... would like to see more usecases, but it might make sense
