Keep track of visibility and ensure the cursor can never be
filled when hidden. This should finally end any issue with the
cursor and visibility with the new focus system. Didn't see this
previously until working on Edi's bottom panes which caused redraw
on resize of the widgets.
@fix
widget operations use NULL terminated strings, backend does not.
Refactor some selection code so all selection deletions trigger
undo events (except where they should not).
