Does that include in raster images as well? Both for SVG and for HTML? So if I have a PNG with a transparent center and click, the click goes to the image and not the underlying object? Interesting. Are we aware of any issues with this?

Opacity has no effect on hit-testing (until we define the value that makes it so, which we've discussed for a little while). ~TJ
