/// pqGenericPropertyWidgetDecorator is a pqPropertyWidgetDecorator that
/// supports multiple common use-cases from a pqPropertyWidgetDecorator.
/// The use-cases supported are as follows:
/// \li 1. enabling the pqPropertyWidget when the value of another
/// property matches a specific value (disabling otherwise).
/// \li 2. similar to 1, except instead of enabling/disabling the widget is made
/// "default" when the values match and "advanced" otherwise.
/// \li 3. as well as "inverse" of all the above i.e. when the value doesn't
/// match the specified value.
/// Example usages:
/// \li Stride, Seed, MaximumNumberOfSamplePoints properties on the Glyph proxy.
