Remove the last use of passing width into Dash by having the Pane with the previews scaling dynamically and relying on Clutter scaling. If we only have one workspace, don't display a selection frame for it. Rework Dash into a searchArea and sectionArea, which get explicitly sized by overlay.js. We use the workspaces size to choose the size of those dash areas. Switch dash colors/boxes etc. to ones from shell-black02. Add a gradient to the panel. Add a magnifier.svg for use in search.
