Spherical layer primitives

[Max Murtazin]

Looking through some parts, noticed that there is, surprisingly, no sphere layer primitives. I think it could be useful for cases, which uses spherical geometry other than the full sphere, half, quarter or 1/8. So, here I present those. 

General naming scheme is n-16sphely. n-16 is used same way as in flat circular primitives, and can be n-8 or n-4, while y stands for the layer of sphere. Picture below shows layers from 1 to 4, left to right:
   
   
   

When put together, they form a sphere:
   

Crude prim files attached (no condlines rn)

These are all cones so cone prims can be used with the right size and transforms.

Not really. First, these have the specific ratios to be used as sphere segments. Second, these primitives would have the conlines shaped properly to fit the parts of sphere. Third, these primitives can be given the high-res counterparts to be rounded in the high-res mode in software like LDView
