RenderListener (Geotools modules 31-SNAPSHOT API)

All Known Implementing Classes:

RenderingTask
```
public interface RenderListener
```
A RenderListener is notified each time a feature is rendered and each time an error occurs during rendering. Therefore VERY LITTLE WORK should be done in the listener!!!

- Method Detail
  - featureRenderer
```
void featureRenderer(SimpleFeature feature)
```
    Reports that a specific feature has been rendered. The same feature might be reported multiple times, if
  - errorOccurred
```
void errorOccurred(Exception e)
```
    Reports a rendering error. The rendering is not normally stopped on it, a listener that wants to stop it can call GTRenderer.stopRendering()
  - layerStart
```
default void layerStart(Layer layer)
```
    Event issued when the layer begins rendering.
  - layerEnd
```
default void layerEnd(Layer layer)
```
    Event issued when the layer completed rendering. May not be issued.
  - labellingStart
```
default void labellingStart()
```
    Event issued when labelling starts. May not be issued if there are no labels to paint.
  - labellingEnd
```
default void labellingEnd()
```
    Event issued when labelling ends. May not be issued.
  - renderingComplete
```
default void renderingComplete()
```
