Detailed Description

Base class for renderer settings widgets.

WORKFLOW:

• open renderer dialog with some RENDERER (never null!)
• find out which widget to use
• instantiate it and set in stacked widget
• on any change of renderer type, create some default (dummy?) version and change the stacked widget
• when clicked ok/apply, get the renderer from active widget and clone it for the layer
