I don't think a filter is called for - it would require a huge amount
of resources.

A QWidget can be in one of three states - active, inactive, and disabled.

Hmm, if you set up the palette with qtconfig, it kind of works..
inactive windows can have different colours for their widgets...

But either qtconfig is buggy, or I just don't understand it. I can't
quite get it to use the palettes I set.

Anyway, the inactive palette is very similar to the active, by default.
I think we can make KDE set the inactive palette to look slightly
'greyed out' (less contrast - not like 'disabled') and we have the
nice effect of inactive windows being less 'obvious'.
