Summary: The new slide effect tries to separate each virtual desktop as much as possible. This separation makes the new slide effect more intuitive than the old one. Test Plan: * switch between virtual desktops * or, move a window to another virtual desktop Reviewers: #vdg, #kwin, #plasma, graesslin, ngraham Reviewed By: #kwin, #plasma, graesslin Subscribers: mart, graesslin, abetts, ngraham, plasma-devel, kwin Tags: #kwin Differential Revision: https://phabricator.kde.org/D9638
