Icon handling. Each icon is defined as in the following example:
icon ID!~overlap icon ID!@image link target
Values for an icon ID containing "*" are treated as text, with the letter(s) before "*" as width prefix(es).
No limit on overlapping icons or text; just separate them by "!~".
Parameters can be added after every object, separated to the left by "!_". This, if there is a link, must be after the link.
Parameters for individual objects in an overlapping stack can also be added, separated to the left by "__".
Unless a link is provided, each cell will have mouseover text indicating its contents.
