Idea: Draw could have a boolean to render on every change. This would be good for building, testing, changing variables in inspectors.
Otherwise, it only renders when tick is hit, which is good if you are updating a bunch of variables with timeline etc.

Thinking about it a bit, we don't need this.
In pd there is an x-to-bang node which is a common pattern to make a cold port hot.
We could do the same thing, wiring the last command to tick, so any change would first hit command, then tick.

I've understood replying the case here:
It works when I change a Vector coordinate, but doesn't when I change the color on FillStyle. To that work we need to parse the commands each time Draw receives a command. However, if we do that, we break with "parse only on tick". Maybe we really need that boolean :-) What do you think?

Even with this, you need to set the every IIP before the vector IIPs, or you get the commands before every is set! Race 😖 meh. At least we need noflo/noflo-ui#111
