Sorry, I made a mistake in my previous email, s/function/block/.
Your new patch is nicer, i tried to improve it a bit, try this one.
I modified the info provided to get rid of the need of i18n, but i'm still
unsure about that.
It still has an issue since layout_status_update_pixel_cb() is always called
even when pixel info is hidden.
