If it's about mouse binding in [gemwin], the math is really heavy,
particulary if the camera is moving.
It can be solved differently by rendering the polygons in an hidden
frame or another gemwin, and set a different color for each new polygon,
the binding will be about detecting color under mouse cursor with the
help of [pix_snap] and [pix_data] and it will work even if the camera is
moving.

I think so for point in polygon, see attached. It's an old attempt of
mine, with a mechanism to draw polygons in Gem and then tell in which
polygon your mouse pointer is.

Did someone here solve this in Pd before?
