Hi Berry, We have a user agent parser that extracts the rendering engine and version from the browser useragent. I only apply the workaround (width=height=255px) to IE version 8. Watch out for non-IE browsers which claim to be IE, as historically some webservers only supported IE.
We set coordsize to 1 1 and coordorigin to 0 0 if I recall correctly. Apparently this works around some VML coordinate bugs. VML is happy to overflow. We now implement all hit detection in javascript. This allows layers to "play nice", so we can click through an SVG or canvas element's bounding box. I haven't yet converted to use Canvas by default, but as you.indicate this may be mucb faster than SVG.
