So it does. There doesn't seem to be ANY way of changing the mask from within pcb, though. The Xaw, Gtk, and HID versions all have a ChangeObjectMaskSize() function, but none have *any* calls to it. However, having created a suitably edited PCB file, and seeing the via with the mask, I note that the via's mask continues to be shown when the via itself is not, in both the Gtk and HID versions.
