A FrameView is a subclass of a BView that draws a simple beveled
rectangle just inside the view's bounds.
The bevel_style parameter is currently unused--the only style available
is a 1-pixel inset bevel.
The contents of the view are erased to the "view color." The left and
top edges are drawn in the view's high color and the right and bottom
edges are drawn inthe view's low color. You may set the high, low,
and view colors after creation to customize the FrameView's look.
