I think bulia has it halfway here. I think we will need to allow for
it since many users try to use it that way. However, we'll have to do
it "right". What he pointed out will have to be addressed.

One thing is that as we move more towards using style (CSS styles),
we'll have to preserve that in the workflow as much as possible
also. When the picker is over our own canvas, it should eventually
get CSS style name (when present) which in turn references and
includes icc-color() on properties.

When it grabs something else (from another app's window) we could
grab it as RGB, or we could possible find a current document stye
that contained the same one. The latter would be a more complex piece
to get right though.
