RE: Determining the Viewport for an SVG Element

I’d hope we can address patterns in the effort to get non-scaling (and maybe better more broadly defined as non-transforming) line widths, patterns and line styles/dash-patterns.

Would this apply to things like <pattern> also?  I have seen a few people ask on Stack Overflow about how to prevent patterns being affected by the viewport transform because they were trying to use SVGs in their responsive web designs.

(Independent of all this, I’m also interested: have there been any discussions of scale/zoom independent font sizes, similar in desire to vector-effect:non-scaling-stroke?)

Cancelling (or partially cancelling) the effect of a transform on a given element was discussed at the last F2F meeting, see the proposal [4]. It's been accepted for SVG2 [5], the action for adding it to the spec hasn't been completed yet.
