Comment 2 for bug 625362

Thanks for the tip, I known the clip function but I never though of using it in that order. And indeed, this is simpler with 0.48 with the option activated. But this could be simplified by this button activating an inner drawing mode when tracing. In back-end, it would a clip function, but for the user, it would just be 'drawing inside'.

And thanks for pointing out bug #394475, also a potential handy improvement for the clip feature.
