UI: Darken the backdrop of navigation gizmos.

Bright backdrop would get lost when having bright elements/background in the viewport.
This makes it use a darkened/lighten version of the theme space header color.
Since icons are colored using the 'text' value of the Theme Space, it's likely that any
theme is going to have a contrasting background color, but just in case darken/lighten it slightly.
