An Anchor is a point where a two-dimensional object, such as a Pic, attaches to
other such objects; you can also think of it as a “pin” that attaches a Pic to a background.
For instance, a Pic may have its Anchor at its center; the Pic may then be attached
to a larger image at that image’s TopLeft (another anchor), so that the center of the
first Pic is located at the top left-hand corner of the second Pic.
The companion object of this class provides several standard Anchors and
a class Anchor.Absolute for creating new ones.
Anchor objects are immutable.
This trait has an alias in the top-level package o1, so it’s accessible to students simply
via import o1.*.
