Comment 4 for bug 775847

I think the question here is themes (see bug #748676). With (Rad|Amb)iance, draw the panel background upside down is enough to represent the pressed state.

At moment, when using other themes, a dark overlay is drawn in home button. This is not much noticable with dark themes. The move of ubuntu logo makes it more visible.

I think the glow around the logo will not be too much visible too when using brighter themes.

Let's wait for design feedback anyway.
