"Change Set:		SystemWindowDropShadowRemoval
Date:			29 May 2019
Author:			Tim Johnson

In (at least) Squeak 4.4, if the preference #menuAppearance3d is set, then SystemWindows too will draw drop shadows.  This changeset stops that behavior and also removes all drop shadows from all existing morphs.  Menus should continue to honor the #menuAppearance3d preference even after this changeset is loaded, but this has not been heavily tested."!
