Let us make it an acceptance test then; ie when we can do this smoothly we will

I don't understand "the next step"; what do mean by checking features to decide
if the style is active?
I did expect a series of "instance of checks" in the renderer; with it skipping
any layer it does not know how to handle.
Do you mean this?

> (!currLayer.isVisible()) {
Because Layer.isVisible() is defined?
You probably mean this:
> FeatureType ftype = mapLayer.getFeatureSource().getSchema(); for
> (FeatureTypeStyle fts : styleLayer.getStyle().featureTypeStyles()) {

For that case I do expect only FeatureLayer to be used (so an instance of
FeatureLayer is valid; there should be no need to create a MapLayer?)
Am I missing something?
