Region shape: freely draw a region shape to support irregular shape
[requested during presentation at Prof. Alison Noble's group at IBME (Oxford) on 19 June 2020]
Medical imaging annotation often requires spatial annotation of irregular shape (e.g. cerebellum) and it would be very useful if VIA3 can support drawing such irregular shape. The existing polygon shape is not practical to be used in these cases.
