[OpenLayers-Dev] SVG2 and 2.11

[Tim Schaub]

Thanks for the explanation Andreas.  I think this would make good detail 
for the release notes.

After 2.11, I think it would be worth trying SVG2 as the default.  If 
there are benefits and no (serious) issues, I think we could push the 
SVG2 code into SVG (bringing the benefit to folks without having to 
change any build profiles).  Then we could deprecate SVG2.
