Allow shell-theme tweaks

[HackaN]

I am working on a shell theme which incorporates dpt. But I would like to be able to theme it a little from the gnome-shell.css. I am trying to find the right class with LookingGlass but so far I haven't been able to change anything. I have managed to theme #panelBox which is fine at the desktop, but it is totally unaware of when the overview is open where I am aiming for a different effect.

Before I used to be able to tweak the #panel between :solid, :transparent and :overview. Would it at all be possible to do something like that again?

DPT predates the Shell's modifiers like :overview, instead it uses specific CSS classes. Assuming custom coloring isn't enabled...

dpt-panel-maximized (maximized state)
dpt-panel-unmaximized (unmaximized state)
panel-transparency (used in the overview)
