Noah Petherbridge fee6e1e105 New widget: ColorPicker, plus other changes 
New properties are added to EventData for Supervisor events:

* Widget: a reference to the widget which is receiving the event.
* Clicked (bool): for MouseMove events records if the primary button is pressed.
* func RelativePoint(): returns a version of EventData.Point adjusted to be
  relative to the Widget (0,0 at the Widget's absolute position on screen).

Other changes:

* Destroy() method for the Widget interface: widgets that need to free up resources
  on teardown should define this, the BaseWidget provides a no-op implementation.
* Window.Resize() will properly resize a Window.
* Window.Center(w, h int) to easily center a window on screen.
