Description:

When a tree of graphical components is saved to disk (translated to ASCII), it is possible to enable the output of point-lists first as 'pts' records, to allow for compression of replicated point lists within a single document. When reading these documents back in, the istream constructor of OverlayIdrawComp (and other top-level components) uses this mixin to manage a table of point lists, building it up as each 'pts' record is read, and accessing entries for each ":pts id" field found in subsequent records.
