Detailed Description

RAII owner of a single VIEW_OVERLAY.

VIEW::MakeOverlay() already registers the overlay with the view, so it must be removed exactly once and never Add()ed again. Getting that wrong leaves a dangling R-tree entry that the next repaint dereferences. Centralising the make/remove pair here keeps the invariant in one place. Derive from this to own a diagnostics or marker overlay.
