[OpenLayers-Dev] SVG2 and 2.11

[Andreas Hocevar]

Hey Tim,

I don't have links available, but the parts of the discussion that I recall are probably the ones you are asking for. See answers inline.

The only workaround that's really gone is the limitation of the allowed coordinate range, with all the weird feature clipping and unrendered / incompletely rendered feature handling.

It works everywhere I have tested it (recent Chrome and Safari versions, iOS, Firefox 3. It may not work in Firefox 2.x.

Features are not re-rendered on zoom level changes (performance boost!), and are immediately visible when they pan into view.

Again, I might have (or likely did) miss discussion on the list about this.  I see that a decision was made on the ticket, and I'm not necessarily suggesting we revisit that decision.  I think the information would be useful for the release notes if nothing else.

Personally I'd love to have SVG2 as default SVG renderer, but since we haven't done so long enough before the release so we can get testing feedback from users, I'd say it would not be wise to do the switch for 2.11.

Having said that, I think adding the information we have now to the release notes makes sense.

If you think that the information I provided above is enough please let me know, and I'll add it to the release notes.

Andreas.
