The default event handler fired when the "constraintoviewport"
property is changed.
@method configConstrainToViewport
@param {String} type The CustomEvent type (usually the property name)
@param {Object[]} args The CustomEvent arguments. For configuration
handlers, args[0] will equal the newly applied value for
the property.
@param {Object} obj The scope object. For configuration handlers,
this will usually equal the owner.
