XTerm shaded property

[felix]

Dears,

I use Xterm's title bar for progession and lot of other monitoring uses:

for progress in {0..100};do
    printf '\e];Job progress: %3d%% \U2595%b\U258F\a' \
        "$progress" \\U2$(( progress ? 581 + progress * 100 /1428 : 800))
    sleep .03
done

And I know, I could use "printf '\e[2t'" for iconify and "printf '\e[1t'"
for de-iconify my window.

But for ``shaded'' property, I have to use `wmcrtl`:

  wmctrl -ir "$WINDOWID" -b add,shaded

I've tried to not use `wmctrl', but I'm stuck finding a way to
correctly change "WM_STATE(ATOM)" X property, by using

  printf '\e]3;WM_STATE=WM_STATE_SHADED\a'

Is there a way to doing this?
