The accessor graph-pane-direction
accesses the direction of the graph graph-pane. If the layout-function of graph-pane is :top-down
or :left-right
then direction is :forwards
. Otherwise direction is :backwards
.
The setter (setf graph-pane-direction)
maintains the dimension of the layout-function but potentially reverses its direction.
