[zbiplot] incompatibility

[porres]

This uses a bang and needs lua graphics I guess, same as with [circle]

Though I really think that PlugData could have an option or a mode that preserves the design of the original Vanilla objects. The bang button changes a lot in proportion! It's kinda like the same iussue with [knob] and this affects the patches. Anyway, I can open a new issue for that.

While we're at it, [zbiplot] keeps flashing and it doesn't in Vanilla, but this is some sort of issue with [bng] behaviour in plugdata that needs investigation.
