No, They use a tag "ok" which is set to 0 when the image content change.
Then when we need to draw them, if the "ok" flag is ==0 than the scopes are
updated before drawing (blocking the whole UI). Updating the scopes set the
"ok' flag to 1.

Than maybe the better would be to add themes options for the backgroung and
grid colors for the scopes.
