Add a comment about the use of the transparent background and set its opacity to 0

Add a comment about the use of the transparent background to catch clicks
in the workspaces area when the dash panes are being displayed and dismiss
the dash panes.

Set opacity for the background to 0 instead of using a transparent background
color so that Clutter optimizes the drawing of the background actor.
