Hi,
do you want to click single elements in your distorted plugin/hotspot?
that's not possible yet, because to be able to draw the plugin distorted,
it will be rendered into a bitmap, and this bitmap is used for rendering/displaying,
and there is no connecting between the rendered bitmap and the original
plugin,
to make is even possible, it is necessary to catch all the mouse events
over the distorted bitmap, remap the mouse coordinates from 3d space
back to the 2d plugin space and send the modified events to the plugin,
not so easy but doable of course

but I hope I can provide this functionality in one of the future releases,
best regards,
Klaus
