BackdropGen v1.0 Blender 3.0 Geometry Nodes

It was created around the time we learned the geometry node. It's a bit cumbersome, but I use backdrops a lot, so I've provided some parameters to give them some versatility.

Refer to the GN of this Tsukimi chick and connect the mesh from the curve.

Since it is simple, we will distribute it for free.
