----- Is it possible to create this mask shape effect in FCP X?

Question

I've been playing around with some masks in FCP X, but I cannot figure out how to create this effect..is it possible?
I am interested in creating a mask shape where I can use it to identify something on the screen inside the shape with the surrounding area darker.
In FCP 6/7, I used to just add a slug on top of the clip, add a mask shape, tweak it, invert it and lower the opacity.
Any thoughts?
Thank you.

in FCPX no masks nor additional tracks needed:
select the clip
in the Info board, select the Color Correction
there's a built-in Mask tool - select that
switch on the Color Board, here comes the trick: …
you are allowed to select WHERE the correction is applied: inside or outside the mask
(in my German interface Innen/Außen)
drag down the general exposure
there are handles to define size, shape, position
you can drag the outer circle (no handles) to define blurr gradient
you can even animate that highlight by key-framing it ....
with the same tool, you can e.g. apply super-fast some simple 'grading' such a 'CSI Miami-style Blue Sky':
