Cannot set CIRCLE_RADIUS=0

The usefulness of setting CIRCLE_RADIUS=0 is mentioned in the Circle Mode page and is a good thing to be able to do.

However, in DroidPlanner, it can be set no lower than 1.
I need to be able to change the radius to 0 for getting smooth panoramas and to 10 for goot POI filming.

Can the validation for that parameter please be updated to allow zero?

Please post this as an Issue on Github:

We will fix it, just need to be reminded via the issue tracker.

thanks, just did!
