This function will clip the object $obj to the area occupied

The color of the object being clipped will be multiplied by
the color of the clipping one, so the resulting color for the
former will be "RESULT = (OBJ * CLIP) / (255 * 255)", per color
element (red, green, blue and alpha).
Clipping is recursive, so clipping objects may be clipped by
others, and their color will in term be multiplied. You may
not set up circular clipping lists (i.e. object 1 clips
object 2, which clips object 1): the behavior of Evas is
undefined in this case.
Objects which do not clip others are visible in the canvas as
normal; those that clip one or more objects become invisible
themselves, only affecting what they clip. If an object ceases
to have other objects being clipped by it, it will become
visible again.
The visibility of an object affects the objects that are
clipped by it, so if the object clipping others is not shown
(as in \@ref evas_object_show), the objects clipped by it will
not be shown either.
If $obj was being clipped by another object when this function
is called, it gets implicitly removed from the old clipper's
domain and is made now to be clipped by its new clipper.
Note: At the moment the only objects that can validly be used
to clip other objects are rectangle objects. All other object
types are invalid and the result of using them is undefined.

weights to how much of its size to allocate for them in each
