Overview: dim the background with the dim-factor property

Browse Source 
Doing this rather than overdrawing a black rectangle saves us
(pixels in screen) * 8 bytes of memory bandwidth for every frame we draw going
into the overview.

It also allows us to dim the background on non-primary monitors making the
overall overview appearance consistent across all monitors.
