Not me. Although I am of course caught up in preparation.
I've made the kind of posts that you've made here, in your last 4 posts, and nobody responds to them as a rule.
They're like non-sequitours. For myself, I've found that if there is something exciting (in a generally understandable sense -- I mean eg. spline
interpolation is pretty nifty, but hardly anyone knows much about it here.) and some aspect I can show to be a major benefit, I might get responses. Otherwise I just put it in my git commit-log.
Personally I am not in a position to test Pixe, since it doesn't yet run on Linux. If that changes, I shall certainly try it.
Suggestion: PoTrace support, for better auto-AA of single-color regions. Unless you actually vectorize things in your AA filter, it is always going to have less quality than a good tracer like PoTrace (with the tradeoff of staying slightly truer to the lines)
I've implemented this myself, by shelling out to potrace, connecting to its standard input and output to feed input image in and get output image, and requesting '--pgm' output format.
http://potrace.sf.netProbably not so realistic suggestion: 2d inverse kinematics (IK). Usable for getting consistent proportions when animating, and
determining when a pose is physically impossible. Sort of like a stick figure, without gravity but with tension between line joints and adjustable proportions. (I was thinking that eg.. if the user resizes the head to match their character, the proportions of everything else should be scaled to keep the same proportion; and if they really want to adjust proportions (eg big head) they can do that with say ctrl+drag)
With a base skeleton according to some of the figures here:

Yeah, complicated idea. Even if it didn't have IKA or proportion adjustment, just the ability to rotate the component lines without changing their length, that could be an effective animation aid.
