The Graphic Overrides in the Property Sheets Box

The Graphic overrides option set up a hierarchy of graphic overrides for different sprites. [An advanced user is needed to explain what this means. This section needs in-depth explanation and possibly an example.]. The option opens up a new Graphics overrides box as well as four new buttons.

The Graphics overrides box presents the available landscape types that can be used to create an override graphic [An advanced user is needed to explain what this means].

Remove override. This unlabeled button removes the selected landscape type from the graphics override box from overriding the landscape type in the LandscapeType box. [Is this correct?]

Add override. This unlabeled button adds a new landscape type to the graphics override box so that it can override the landscape type in the LandscapeType box. [Is this correct?]

z. This sets the override hierarchy. The higher the z value, the later the landscape type in the graphics override box will override the landscape type in the LandscapeType box.

Add override. This unlabeled button, which is to the left of the other three buttons, also adds a new landscape type to the graphics override box so that it can override the landscape type in the LandscapeType box. [This seems the same as the second button. Is this correct?]
