It turns out restoring all operation state from the moment Defer
is executed is too much; for example, a right-click pop-up needs
the transformation, but not the current clip.
Change Defer to only restore the transformation, and reset all
other state.
Other combinations may be needed in future; we'll deal with them then,
possibly by exposing the load state mask.
