Update of /project/eclipse/cvsroot/eclipse In directory common-lisp.net:/tmp/cvs-serv21678

Modified Files: move-resize.lisp global.lisp Log Message: - The screen edges resistance is implemented. To configure it use *screen-edge-resistant-p*. Set it to nil if you don't want to feel any resistance when attempting to move a window outside the screen boundaries. Default value is t.

- The window edges resistance is also implemented. To configure it use *standard-window-edge-resistant-p*. Set it to nil if you don't want to feel any resistance on edges of window(s) you are about to overlap. Default value is t.
