Nodes partial Mouse transparency

[Pavel Safrata]

Hello Hervé,
no, it's not possible to have a visible parent which is mouse 
transparent but its children are not. It is not really a common request. 
What about this:
- Have the container invisible and not pickable. In the specific case of 
Pane it is enough to set pickOnBounds to false and fill to null, you 
don't have to use the collapsed size. Or just use Group which behaves 
like that by default.
- Represent the visuals you want to have there by a child node (such as 
Rectangle or another Pane) which is visible, and has mouseTransparent 
set to true.

This is reasonably clean but creates some extra nodes so its usefulness 
depends on the number of such instances in your app. Would it be usable 
in your case?
