+// primitive: none (default), triangle.
+// background-color: black (default), red, green, blue.
+// primitive-color: black (default), red, green, blue.
+// opacity: [0.0 - 1.0]. Default is 1.0.

+// Whether the plugin accepts touch events or not can be customized using the
+// 'accepts-touch' plugin parameter (defaults to false).
