[idea] Add squircles

[Probioticz]

why not? squircles are so fun why not add it

(you could also add the new corner shape svg thing as a category in the relgtcnae tool)

We have rounded rectangles

But it's not squircles

In reallity, there's a new css and svg thing that can do "custom" borders like bevel, scoop, rounded, squircles and one more. This could be added to the rlgenctae tool.

paper.js cant make these so it would be more likely to be added to the shapes tool instead
