Invalidate the item at the specified index.
ImageViewer.prototype.invalidateItemByIndex = function(index)
invalidateItemByIndex(index: number): void;
0-based index of the item to invalidate.
Calling this method will cause the viewer to re-render the item. This is performed internally by passing the value obtained the value of GetItemViewBounds for the item and if it is not empty, passing to Invalidate.
