[0.16.0.0] Inconsistencies with Canvas Spheres, Domes, Cylinders, Tubes, & Holes

The canvas sphere, dome, cylinder, tube, and hole items are all plagued with inconsistent design/modelling choices such as inconsistent scales and polygon counts

In trying to model some more arches along the upstairs terrace/balcony of Courtyard Villa, I ran in to this issue in which Canvas Holes and Canvas Tubes do not mesh together seamlessly, and as such leave a rough seam in the space between them

In trying to model the corner parapets of this bouncy castle, Canvas Domes and Canvas Cylinders do not immediately align properly, so either the Dome or Cylinder need to have their scale parameters fiddled around with until there is minimal seams between them
