An issue you'll have with perspective transforms is that they don't generally commute with Bezier curves.
IOW, the perspective transform of a Bezier curve obtained from some controls points in NOT in general the same as the Bezier curve obtained from the perspective transforms of the initial control points.
I haven't used Xara Extreme, but if it does perspective, it would likely be with beziers since it's for SVG too, wouldn't it?
Now that's stringing a lot of unverified hypotheses, is that not, just to deny somebody's word ?
FYI, a link to a forum thread where the matter is discussed in more detail (Note : 'quartic' and 'cubic' Bezier curves are particular cases of 'polynomial' Bezier curves).
