SVGStyleElement - deprecate 'media' attribute

w3c/svgwg#1022

karlcow: media attribute isn't deprecated HTML. So makes no sense to remove it from SVG.

karlcow: should we keep it and close the ticket

Vinay: It should be fine. Lets close the bug

RESOLUTION: Keep media attribute in the spec and close bug as HTML still has the attribute as well

Should getBBox returns values when the shape can't be drawn

w3c/svgwg#1018

<nzimmermann> sorry for being late, we had a power cut :-(

karlcow: If with or height are negative, we should make everything 0 in getBBox

karlcow: ...according to last resolution

dmangal: We should not throw if there are invalid values.

dmangal: I am concerned what we should return: everything 0 or only the width/height dimension turn 0

dmangal: an element with 0 dimension does have a bounding box according to spec

dmangal: according to the paragraph in qiuestion. Should we change the paragraph?

karlcow_: The resolution shouldn't have any affect on the rest of the SVG document IMO

karlcow_: Putting everyhthing to 0 seems to be simplest

nzimmermann: Most obvious would be 0 everything.

nzimmermann: Elements with 0-dimension doesn't have an effect on parent bounding box.

nzimmermann: So there is no value to keep position and make dimension only 0

nzimmermann: seems to be natural to return 0

dmangal: A path can be 1 dimensional. Would that be different?

krit: M 100 100 L 100 100 as example

nzimmermann: valid question

nzimmermann: we should test this scenario

karlcow_: We should create WPT tests first and see what browsers return and decide based on the results.

nzimmermann: there is no way to fill a dot. But of course we can stroke it. SVG2 does have arguments for getBBox. So maybe one can differentiate between getBBox w/o arguments and an argument for getting the stroke boundingbox

nzimmermann: We should test these scenarios. Agree with karlcow_ : we should base our decision on the results on WPT.

karlcow_: Who'll create the tests

dmangal: I will

ACTION: dmangal will create more detailed getBBox tests for WPT and also take the arguments into account.

karlcow_: The paragraph you found almost looks like an algorithm. There are many places in SVG2 where things are said but not written as algorithm

karlcow_: it is strange to me.

dmangal: It seems off from the rest of the paragraph

TPAC breakout session

karlcow_: If there is anything you'd like to discuss at TPAC let me know. The breakout session is at the end of the day.

ACTION: Add breakout session questions and send them to Karl
