// IconListClass is ListClass plus the option to include an icon on each line entry,
// the option to have the class maintain its own copies of strings passed to it
// for display, and the option to limit the maximum number of these strings that are
// kept (entries are removed from the top when this maximum is reached).
// Also added: multiple item selection capability. Note that the old selection code
// runs as normal, but it simply not used when it comes time to display.
// Also added: if mem. allocation is being done by this, the ability to break new items
// into multiple lines of text is enabled.
// Also added: extra data can be invisibly stored with each item, if memory allocation is
// being done by this.
// Extra data included 3 item preceding icons, 1 fixed position icon, an extra string,
// an extra void pointer, and a color remapping value.
