Steps to reproduce this

Steps:

1. Create geometry with a circle in it: buildGeometry(() => circle(0, 0, 100)
2. Don't actually draw the returned geometry

It draws to the screen anyway and the returned geometry has 0 vertices.

This is because some 3D primitive drawing functions call _drawGeometry(), which is currently a function that the renderer calls after it's checked if a buildGeoemtry is in progress. So circle and other methods that directly call _drawGeometry need updating.

Snippet:

function setup() {
  createCanvas(400, 400, WEBGL);
  geom = buildGeometry(() => circle(0, 0, 100))
  console.log(geom.vertices.length)
}
