SVG needs to support SVGError events and some form of "error state"

The spec calls for implementing an "error state":
http://www.w3.org/TR/SVG11/implnote.html#ErrorProcessing

"A highly perceivable indication of error shall occur. For visual rendering
situations, an example of an indication of error would be to render a
translucent colored pattern such as a checkerboard on top of the area where the
SVG content is rendered."

Most desktop browser authors would consider such error behavior complete
lunacy, given the current expectation of web content authors for browsers to
silently render any erroneous HTML page.

Regardless, we should have some way to display errors to the content author,
even if we silently render erroneous content nicely for the end user.  One
possible solution would be to leverage an error console, such as is described
by bug 10361.
