You mean [1]? If all bitmap image rendering is done inside SVG/VML
instead of HTML, it should indeed work to handle events on layers
below a vector layer. But only if there is no graphic object "in the
way". So if you click eg. on a vector polygon, the event still will
not bubble through. I do not know if this can also be changed by
different event handling.

So what would have to be done is to move all layer rendering in
OpenLayers into a single SVG/VML container. This would also be a huge
step towards the solution of [2].

Andreas.
