Thank you James.

**********
Latest version of squircle_FG.js:
The only change is that the variable radval is now changed to input variable radius, throughout the node.
This was done because radval was showing up in the Info panel, in addition to radius.
(radval = radius, so radval is not needed.)

I did not change the name, so suggest replacing old squircle_FG with this newly modified one, for the 5 people who recently downloaded the former version.
