// don't share a common interface, which is what makes this a mess), and so
// functions here "common" to imageCompareBase and patternWindow like
// getImageFromIndex and setCur can't be virtualized into a common base.
// getImageFromIndex could/maybe should be templated and factored down, but
// setCur can't be - we could template this code as well and pass a
// doubly-templated functor to call the right setCur on the right object, but
// yuk. Live with the duplication for now.
