 /* FIXME:
-   - panel should be black and/or more subtle in :overview
    - bottom-border for panel seems transparent rather than the given color
    - white edge highlight with text-shadow and icon-shadow for panel-button
    - better shading of the panel (dark 5%) - impossible without multipoint gradients, image-bg is a hack
