The following examples show how the base sprite, the optional sprite, and the over sprite are displayed when the values of the Plot Last and OverIsTop buttons are changed.

In this example, is forest pine landscape hex. As can be seen it has a base sprite (the image over the left-most sprite button) and an optional sprite (the image over the middle sprite button). However, there is no over sprite (i.e., no image over the left-most sprite button).

Initially, the Plot Last button is set to false, which means that the optional sprite will not be seen.

However, if the Plot Last button is set to true, the optional sprite now overlays the base sprite
