When blur is disabled, shortcuts overlay and alt+tab switcher is completely transparent.

[Michael Rawson]

TEST CASE:
1. Open ccsm
2. Go to unity plugin settings Experimental tab, set Dash Blur to "No Blur" (disable)
3. Press and hold the Super key
   -> The shortcut overlay should not be completely transparent, but darkened.

Original description:

If you disable blur entirely in CCSM or other, the shortcut overlay (and the alt+tab switcher) becomes completely transparent, as opposed to the dash's darkening.

It makes it inconsistent and very hard to read.

Hello Michael, or anyone else affected,

Accepted unity into precise-proposed. The package will build now and be available in a few hours. Please test and give feedback here. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you in advance!

The overlay & alt-tab are now colored ala the dash so this bug on no blur is fixed here
