Subject: Composing buffers with zero dimensions

Hello,
I have tried a couple of tests with the latest version of gegl. I encountered
problems with composing operations when the ROI was zero.
Try e.g. gegl/docs/gallery/drop-shadow.xml and modify the
<node class='crop' x='80' y='60' width='360' height='320'/>
to
<node class='crop' x='80' y='60' width='36' height='32'/>
After this change the whole gegl logo is outside the result and this causes
problems to the <node class='over'> - gegl segfaults :-(.
After adding a test on zero dimensions to gegl-operation-point-composer.c
(patch attached) the problem disappeared.
I suppose that similar check should be also in gegl-operation-point-filter.c.
Or should be the problem corrected elsewhere?
