Module brush 

Gradients and image fills: registered once, named by id wherever a colour can go.

A brush does not fit where a colour fits. A Paint is two words on the wire and a gradient is a list of stops, so the brush travels the way a picture does: registered before anything draws it, kept by the Renderer, and named by id after that. That is the road [crate::asset] already built, and this is a second kind of traffic on it rather than a second road.

The bytes are this module’s own fixed layout and not a file format. No platform stores a list of stops as a document, so a format would be a parser to write, to keep, and to get wrong.
