Florian Müllner ca7c4edd41 windowManager: Update dim effect
The combination of desaturating and lowering the brightness does
not work too well in all cases, in particular for applications
using the dark theme variant. Dropping the desaturation effect and
making the brightness adjustment more profound gives a better
result.
