What a section plane does with the annotations on the side it cuts away:
"hide": they are hidden (the default)
"ignore": this plane does not hide them; another plane can still hide them
"project": they stay visible, drawn at their projection onto this plane (moved along its normal)
Annotations on the side a plane keeps are never affected. With several planes, every "project"
plane first moves the annotation onto itself (a box of "project" planes keeps it inside the box),
then the annotation is hidden when a "hide" plane cuts that position. The drag icons of the
section planes are never hidden by a plane, as the planes themselves are drawn whole; those of the
movable planes keep being hidden by every plane that cuts them, whatever its mode.
A plane's mode reaches only as far as its reach: an annotation
further past the plane is hidden in every mode.
