+    //   Normal   - the normal state of control on the page when it isn't
+    //              focused or otherwise active
+    //   Hot      - when the mouse is hovering over a part of the control,
+    //              all the other parts are considered "hot"
+    //   Hover    - when the mouse is directly over a control (the CSS
+    //               :hover pseudo-class)
+    //   Focused  - when the control has the keyboard focus
+    //   Pressed  - when the control is being triggered (by a mousedown or
+    //              a key event).
