Bug Description

In the past the Background Color opacity setting only affected the Dash as both the panel & launcher have their own opacity settings.
Now the Background color opacity does alter the panel's opacity & actually is the only way to get a fully transparent panel.
To see:
Lower the panel opacity to 0.0000, panel does not go transparent
Now set a very low value for Background Color opacity (1-3 will do
Panel will now go transparent.
Raise the Background Color opacity from the above low value & the panel will become darker (more opaque

This also affects using no blur with a high Background Color opacity for readability & having a panel that's not opaque

Well yes & no, noting this bug was 1st filed on 13.04
There is currently no way to get a fully transparent panel so the fact that opacity of the Background color affects how the panel looks is less relevant.
But yes, altering the Background color opacity does alter the appearance of the panel though in current compiz/unity that may be expected behavior
So in that vein & with a fully transparent panel not possible maybe this bug should be invalid.
