Feature Idea: Swept Surfaces with a Taper

[randompast]

Curves are a very useful modelling tool for procedurally generating a large variety of organic structures. The current Path3D / CSG solution could potentially be improved by migrating to a new GPUPath3D node which could allow profiles and tapers while running with dynamic LOD using tessellation shaders.

Here's where I started the discussion.
