commit 1154a1e8d75f5c9f5af992d82aa2a20f514bafe9
Author: Marina Zhurakhinskaya <marinaz redhat com>
Date: Mon Jun 8 19:04:52 2009 -0400
Add a results pane in the overlay
Display the results pane above the workspaces. The results pane is somewhat
transparent and has a blue gradient background. The dash pane is slightly
transparent and also has a blue gradient background.
The results pane shows up when a More control is clicked. It disappears when
a Less control is clicked, an area outside of the dash area is clicked,
an item starts being dragged, or the overlay mode is exited.
Add shell_global_create_horizontal_gradient() to shell-global.[ch]
