paned: Restrict picking to allocation

Browse Source 
Same reason as GtkViewport does it: We might allocate child widgets
outside of the paned's content allocation. For drawing, we add a clip
node.

This was causing the "Record" button in the inspector recorder to ignore
pointer events since the treeview column header label in the GtkPaned
was swallowing it.
