attempt to make composite effects suck less.

attempt to make composite effects suck less.

Introducing the styles:

 * fast: does not have focus-in/out effect, similar to "slow", but runs in
   0.1 second, so quite fast.

 * focus-out-colored: the focus-out has a color applied to it, the
   color is gray by now, but can be changed with conf_colors (last
   item), one can go crazy and make the focused out yellow or make
   them semi-transparent;

The "comp" configure dialog now the focus in/out effects as well, to
make user know what is happening a boring label is overlaid in the
preview.
