Currently the node tool operator stores the mouse position from
the first execution because it's not possible to retrieve it again from
the operator redo callback which doesn't have access to the event.
However, other inputs like the region size and the viewport transform
are retrieved again for every redo execution. This creates inconsistency
and generally makes redo less useful for node tools than it should be.
Generally tweaking an input in the redo panel should keep everything
else the same.
This commit adds the rest of the inputs as RNA properties just like
how mouse position is already handled.
