Thanks, I'll look at this asap (as I got other stuff "on fire").
BTW, I can't ever get (in fact, I don't know how) working
the coords to be displayed in my traits app.
I guess this is more related to traits, not to mpl.
But the "mpl embedded in traits app guru" is on holydays for now.
Let's wait...
