-<!-- Class -->
 Serves as the base class that defines the properties and methods shared by all types of overlays.
-=== Remarks ===
-The &lt;strong&gt;Overlay&lt;/strong&gt; has a similar concept to that of the Layer. Different types of overlays stack over each other to form a map.Usually, an overlay represents an image with a transparent background that is laid upon other overlay, such as a &lt;strong&gt;LayerOverlay&lt;/strong&gt; or &lt;strong&gt;WmsOverlay&lt;/strong&gt;.There are basically two kinds of overlays: base overlays and non-base overlays.A base overlay has its &lt;strong&gt;IsBase&lt;/strong&gt; property set to true. It is displayed as the background image of the map.A non-base overlay has a false &lt;strong&gt;IsBase&lt;/strong&gt; property. These overlays can overlap the base overlay and/or each other.

-This method draws the Overlay.
-=== Remarks ===
-This method is the concrete wrapper for the abstract method DrawCore. This method draws the representation of the overlay based on the extent you provided.When implementing this abstract method, consider each feature and its column data values. You can use the full power of the GeoCanvas to do the drawing. If you need column data for a feature, be sure to override the GetRequiredColumnNamesCore and add the columns you need to the collection. In many of the styles, we add properties that allow the user to specify which field they need; then, in the GetRequiredColumnNamesCore, we read that property and add it to the collection.
