The get / set image list methods of the list view can work with one of the 3 different types of image lists the list view uses. The methods take one optional argument to specify which one of the 3 types to get or set.
Currently this argument must be the numeric value of the type. This was a mistake I made when first implementing these methods. At the time I was sure that using the numeric value would be easier for the programmer.
However, it is not easier. Using the string name of the type, NORMAL, SMALL, or STATE is easier.
The methods should be enhanced to accept either a string keyword or the numeric value.
