Hi,
While running your changed tests, I think I found new failures. Being a bot and all I'm not very good at pattern recognition, so I might be wrong, but could you please double-check?

A Bézier stroke can lie outside its "defining triangle" for at most half of the stroke width, not an entire stroke width.
But note that the geometry we generate for Bézier outlines isn't quite a triangle (see d2d_geometry_outline_add_bezier_segment()). I *think* this change may still be safe with that geometry, but please verify that.

Yes, I know, I was a bit sloppy in the description, also because I don't really know how to describe that shape: it's a triangle with the "control point corner" removed. But again, the Bézier line is confined in "truncated triangle", so its stroke can exceed it for at most half of the stroke width.
Also, it seems the tests still pass (tested on my computer, because Marvin is currently in a cosmic pessimism phase). And I briefly visually compared the test images, and they seem to be identical.
Giovanni.
