<p><code>GetVisible()</code> returns the state of the visibility flag for a given layer (the check box in the
Layers pane). <code>IsVisible()</code> returns the actual visibility of a layer, based on its visibility flag,
the visibility flag of any groups that include the layer, and whether the layer has a defined style for the
current view scale.</p>
