How to export Art brushes as vector NOT bitmap?

[Acorn]

The fact it's possible at all to convert art brushes into vector was quite a revelation to me, I previously always assumed they were bitmaps.

After some testing I ran into the same issue as everyone else, for example, heavily curved lines no longer convert vectors but become clipped bitmaps. I wonder if there's a maximum number of nodes before it decides to make it a bitmap?

Thank you Jono, this is a useful analysis.

Pity Xara is not around to chip in.
