graphene:rect-offset (rect dx dy result)

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

The graphene:rect-t instance with the offset rectangle.

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