<div class="description">
Adds objects to collection, Canvas or Group, then renders canvas
(if `renderOnAddRemove` is not `false`).
in case of Group no changes to bounding box are made.
Objects should be instances of (or inherit from) fabric.Object
Use of this function is highly discouraged for groups.
you can add a bunch of objects with the add method but then you NEED
to run a addWithUpdate call for the Group class or position/bbox will be wrong.
