Alter definition of cairo_composite_rectangles_t

This is a more useful definition that is able to individually track the
rectangles that compose the composite operation. This will be used by
the specialist compositors as a means to perform the common extents
determination for an operation.

-/* Rectangles that take part in a composite operation.
- *
- * This defines four translations that define which pixels of the
- * source pattern, mask, clip and destination surface take part in a
- * general composite operation.  The idea is that the pixels at
- *
- *	(i,j)+(src.x, src.y) of the source,
- *      (i,j)+(mask.x, mask.y) of the mask,
- *      (i,j)+(clip.x, clip.y) of the clip and
- *      (i,j)+(dst.x, dst.y) of the destination
- *
- * all combine together to form the result at (i,j)+(dst.x,dst.y),
- * for i,j ranging in [0,width) and [0,height) respectively.
