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
