What is kaXmlSVG? Is there such an implementation?
There was a lot of discussion about vector graphics for
overlays: the main issue is we need different implementations for
different browsers (or the use of a third party plugin).
I'm doing experiments with <canvas> in Mozilla Firefox.
Seems to be very powerfull and efficient for small items (as icons and
small lines or polygons) but terribly unefficient for complex lines
and polygons (more than 100 vertex). But this is a very preliminary
And last it works only for Firefox and Mac.
