** The sequence and associated things to show are held in an ordered list

**
** The things to show are displayed around the sequence in the order that
** they are held on the list.

** EmbPShowInfo holds the descriptor (one of EmbPShowBlank, EmbPShowTicks,

** information that could be useful in displaying its type of information.

** EmbPShow could have a list of:
