A BBox is a purely cosmetic and organizational view that draws a labeled border around its (view) children. The border and label are drawn within the BBox's frame rectangle.

• The label is drawn in the current font, which by default is the system bold font.

• The label is drawn in the current high color; the default high color is black.
