/**
SVG "array" style notation for size/layout/alignment.
This is a compact SVG representation of class layout.
It is composed of a minimum of three data points for each member or
base of a class:
- offset index
- size
- align
Including annotations for holes, padding, and
implementation-specified and otherwise invisible objects.
It's constructed by creating vertical columns for each of the data
points specified above, and filling in horizontal rows for each of
the class components.
