inspector: Change semantics of inspector render node notify

Browse Source 
Instead of just notifying the inspector of what is going to be rendered,
allow the inspector to modify it.

This way, the inspector can overlay information it deems relevant over
the render node while still having access to what the actual widget
(without the inspector) would paint.
