Fix bug with Fbo layer clipping
Rendering views with alpha causes the creation of Fbo layers. These layers
are created at the size of the view, clipped by the current clip rect.
However, if the view lies completely outside the current clip rect, the
Fbo layer is created at the full size of the view and copied into place
outside of its container, causing artifacts like notification items showing
up outside the notification panel.
Fix is to note when the intersect() operation fails and to set an empty bounds
on the layer.
