Transparent Menu/playbar for a cleaner Compact player

[Alexis]

Currently  this is the play bar we have for Compact player when not hidden (hovering):





 I would like to see the skinned (white) background that show up behind the items be invisible when hovering:


wherein one sees just the 'x' for closing, square for maximizing, .. same thing for the play buttons.  Etc

This would not apply to the menu items that require a second click. (like the library search menu)
