<trackbot> ISSUE-2201 -- Return value of
SVGAnimationElement.getStartTime unclear -- CLOSED

ISSUE-2201
ED: question is whether the decided upon behaviour was the most
useful to authors
... have implemented the resolution we came to
CL: seems resonable to raise exception if you cant calculate the
starttime
<ChrisL> It seems reasonable to me. if the re is no current
interval, then throw an exception
CMC: you can determine whether it's the current starttime or the
previous interval starttime
... don't mind either way
... CL if you're concerned about whether it's not current...
CL: right, but it's only about whether a begin time could be
determined
ED: is it possible for an author to get the previous starttime?
CMC: perhaps by listening to endEvents
CL: is there information that the impl has that can be given back by
the exceptioncodes
CMC: currently just trhows invalid_access_err
ED: the counter-argument for listening to endEvents is listening to
beginEvents
CMC: for either way yes, the workaround is to listen for events
ED: ok, at least there are workarounds
... fine, the current errata text will be fine
<scribe> ACTION: heycam to do the suggested changes/additions to the
[16]http://dev.w3.org/SVG/profiles/1.1F2/errata/errata.xml#getStartT

ISSUE-2071
<heycam> ISSUE-2071?
<trackbot> ISSUE-2071 -- potential security hole involving
pointer-events, filters, foreignObject, cross-origin IFRAMEs, and
elementFromPoint -- RAISED
<trackbot> [21]http://www.w3.org/Graphics/SVG/WG/track/issues/2071
[21] http://www.w3.org/Graphics/SVG/WG/track/issues/2071
CMC: Robert sent some examples of how one might be able to access
crossorigin content
CL: it's using filters to access a part of the screen that you own
<ChrisL> Opera has getPixel and setPixel on canvas, might be another
way without filters
CMC: right, mozillas blingthing had something similar IIRC
... I think it should probably be tracked per-origin
CL: if you have an svg that brings in a raster image from somewhere
else, then you don't want your filters to stop working
... with some strange securityviolation error
CMC: the fact that filters can use the image is ok, but you might
have to restrict how scripts can access that information
... some ppl have experimented wrapping entire sites in some color
tint filters, and that sort of things should still work
... the particular thing is pointer-events=painted, maybe the
wording could be tweaked to cover that hole
... but it's more of a general problem
CL: exposing pixel values to script is the issue
CMC: one way would be to track pixel per pixel the origin
... the other might be to [fill-in-blank]
<heycam> s/[fill-in-the-blank]/have a single "tainted" flag that
gets set whenever foreign content is accessible via a particular
canvas, etc./
<heycam> ...which would prevent script from accessing any of the
pixels there
CMC: ED did you want to ask your security guys about this?
ED: I think for this particular issue that's raised we weren't
vulnerable, but I'll inquire about the other possible exploits
accessing pixel values
CMC: might be good to discuss at the F2F
<scribe> ACTION: ED to start the discussion on security
SVG/canvas/filters etc with the security-group at opera [recorded in
[22]http://www.w3.org/2009/02/02-svg-minutes.html#action02]
<trackbot> Created ACTION-2431 - Start the discussion on security
SVG/canvas/filters etc with the security-group at opera [on Erik
Dahlström - due 2009-02-09].
ISSUE-2026
ISSUE-2026?
<trackbot> ISSUE-2026 -- Need Test Ensuring that 'class' is
Animatable -- RAISED
<trackbot> [23]http://www.w3.org/Graphics/SVG/WG/track/issues/2026
[23] http://www.w3.org/Graphics/SVG/WG/track/issues/2026
CMC: the rest are issues to create tests, they jsut don't have
actions yet
CL: on svg full 1.2 testsuite, but should probably be 1.1 testsuite
CMC: though we might be able to getPresentationTrait in 1.2 full
CL: seems like an easy test to write
<scribe> ACTION: CL to create an SVG 1.1 test verifying that the
class attribute is animatable [recorded in
[24]http://www.w3.org/2009/02/02-svg-minutes.html#action03]
<trackbot> Created ACTION-2432 - Create an SVG 1.1 test verifying
that the class attribute is animatable [on Chris Lilley - due
2009-02-09].
<scribe> ACTION: CL to create an SVG 1.2 full test verifying that
the class attribute is animatable, relates to ISSUE-2026 [recorded
in [25]http://www.w3.org/2009/02/02-svg-minutes.html#action04]
<trackbot> Created ACTION-2433 - Create an SVG 1.2 full test
verifying that the class attribute is animatable, relates to
ISSUE-2026 [on Chris Lilley - due 2009-02-09].
ISSUE-2018
CMC: this sounds like a tricky one to test
CL: not really
... use cursorkeys and normal keys
... put on capslock and shift, that could be done as a sequence
... though it might be hard if you have a device that don't have
those keys
CMC: ought to be comprehensive, maybe a list of keys that we know
don't generate any text
... doesn't seem particularly urgent
<scribe> ACTION: heycam to create 1.2T tests for ISSUE-2018,
ISSUE-2019, ISSUE-2020 [recorded in
[26]http://www.w3.org/2009/02/02-svg-minutes.html#action05]

[28] http://www.w3.org/Graphics/SVG/WG/track/actions/2165
ED: basically just aligning with 1.2T, minor clarification
... cat3 correct?
CL: seems like a cat3 yes
ED: can we move it to proposed?
CMC: yes, looks
... fine

ISSUE-2113
<heycam> ISSUE-2113?
<trackbot> ISSUE-2113 -- animate-elem-35 -- RAISED
<trackbot> [42]http://www.w3.org/Graphics/SVG/WG/track/issues/2113
[42] http://www.w3.org/Graphics/SVG/WG/track/issues/2113
CMC: comment from someone saying that one of the 1.2T tests has a
problem because it relies on particular precision
... someone should probably take action to analyze this
CL: would it help having an explicit lineto instead of the
closepath?
... also don't understand why it doesn't amp to fixedpoint
coordinates
CMC: might be that the test could be tweaked
... would need someone to go through the calculations
CL: do we know if any of the mobiles use fixedpoint?
CMC: I think so
... if the calculations come out fine in 16.16 we can probably close
the issue
... think the mail there explains why they chose something else than
16.16
CL: what's the company?
CMC: ekioh
... maybe we should restructure the test to run inside some given
precision
... we should know from the implementation report which
implementations pass
ED: though all the implementations were run on desktop, might be
different on device
<scribe> ACTION: AG to see if the animate-elem-35 can be remade to
work under smaller precision fixedpoint [recorded in
