Initial version of a Swing-based variant of the SceneViewPanel, which is

possibly only a temporary workaround intended to allow the scene editor to
work.  BufferStrategy-style rendering only works with Window or Canvas
objects, but the scene editor is a full-fledged Swing application and if
the scene view panel isn't a Swing component then menus and other things
won't render properly on top of it.
