public abstract class FLyrDefault
extends AbstractDisposable
implements FLayer, FLayerHidesArea, LayerListener
```
Implementation of the common characteristics of all layers: visibility, activation, name, ...

Represents the definition of a basic layer, implementing FLayer, and new functionality:
- Supports transparency.
- Notification of evens produced using this layer.
- Can have internal virtual layers.
- Can have a text layer.
- Supports an strategy for visit its geometries.
- Can have an image in the TOC (table of contents) associated to the state of this layer.
Each graphical layer will inherit from this class and adapt to its particular logic and model according its nature.
