To the best of my knowledge, I think you're right: of course Qt should
not need to handle fiducials, so it makes sense that it lacks support
for them. I believe there is an easy workaround that is setting the
type for touch points, that could work for differentiating between
them -- plus you can easily differentiate between fingers and proper
blobs. I'm not sure whether you can add more attributes, like the
angle, to a QTouchPoint, unless you subclass maybe? I'm not very much
familiar with Qt's handling of touch-stuff.

I'd love to see your project expanded to include fiducials, I'll clone
it and tinker a bit with it -- although my project needs to be
prototyped rather quickly so it's likely I'll go back to my old ways
of libCinder for now.

Any thoughts/suggestions, I'll be happy to hear them.
