Greg Brown resolved PIVOT-166.
------------------------------
Resolution: Won't Fix
Fix Version/s: (was: 1.3)
This is by design. Decorators are always clipped to the parent's bounds, since
many decorators need to draw outside the component's bounds (e.g. drop
shadows).
Since decorators use a chained prepare/update model, we can't assume that it is
OK to clip to the decorated bounds in the prepare() phase, since that clip rect
may not be valid for subsequent decorator update()s, and almost certainly won't
be valid for the component itself, which paints into a copy of the final
prepared graphics but must be clipped to the intersection of its own bounds and
the current clip (not the intersections of all preceding decorator prepare()
calls).
As a result, the only assumption that decorators can make is that drawing will
be clipped to the parent's bounds.

> Run the WatermarkDecoratorTest to see this behavior. WatermarkDecorator
> reports the component's bounds in getBounds(), it uses an identity transform,
> and it doesn't alter the clip rect of the graphics, yet the watermark is
> being painted outside the bounds of the decorated component (in the case of
> the test, the decorated component is the CardPane that lives in the
> TablePane's row beklow the line).
