It's the same with most graphical software (like Photoshop) that lets
you paint Bezier curves and also in Gem's "curve" object. You can make
the point that is controlling the curve visible in the data structure
using a marker done with drawpolygon (you already did). You can make
this marker's visibility controlled by a variable in Pd 0.39 and up.
