The following methods offer control over overlays.
Note: Many of the methods in this section use a pos% argument to refer to the position of an overlay in the overlays list. The overlays list is a zero-based list, i.e. the first overlay is at position 0, the second at position 1 etc. This must always be borne in mind when specifying the pos% argument.
