graphene:rect-offset-r (r dx dy result)

r -- a graphene:rect-t instance
dx -- a number coerced to a float with the horizontal offset
dy -- a number coerced to a float with the vertical offset
result -- a graphene:rect-t instance for the result

The offset graphene:rect-t instance.

Offsets the origin by dx and dy. The size of the rectangle is unchanged.
