Greetings,

I have been adding new uv-mesh shapes, and demos for them. The uv-mesh.lisp code still needs some cleaning up.

List of the new stuff, mostly with demos.

• uv-mesh
  +- transform-extrude-mesh
  +-- sphere
  +- function-extrude-mesh
  +- sweep-mesh
  +-- cylinder -- extrude circle
  +-- cone -- cylinder with taper
  +-- rect-prism -- extrude subdiv rect
  +-- pyramid -- rect-prism with taper
  +-- grid
  +-- torus

• point-cloud
  +- make-grid-points
  +- make-random-points

• curve-shape -> polygon
  +- subclass of point-cloud
  +- array of points
  +- make-rectangle-polygon
  +- make-circle-polygon
  +- make-sine-curve-polygon

• polyhedron
  +- make-tetrahedron
  +- make-dodecahedron

• group
  +- do-hierarchy, is-leaf?

• group demos
  +- basic hierarchy, display axes
  +- scatter shapes at points
  +- robot arm

• animation demos
  +- simple translation
  +- cubes in grid random y rotation
  +- animate robot arm flex fn
  +- constraints -- move as inverse of shape -- add-animator-at-end
