Subject: [PATCH] workspace: Move decision to show/hide chrome to clone

Currently the chrome layer decides itself which events on the window
clone should show or hide the chrome, which makes it harder to extent.
Instead, move the decision to the window clone by letting it emit
show/hide-chrome events when appropriate.
