Refs #2190, #2191: Reverted changes that would propagate Visual Mapping values to child visual properties by default; now the values are only propagated if there is an enabled VisualPropertyDependency whose parent VisualProperty is the same as the mapping’s property (this is probably more intuitive to the end user). Also fixed issue where a default value would not propagate to a child property if the style had a mapping for that child property (the related dependency has to be enabled).
