partial torus prims

[Rene Rechthaler]

   
edited the upper picture to fit the p+q suffix
p starts from the center line outwards
q starts from the outermost/innermost and goes inwards
last digit is the number of hi-res segments
(hexadecimal to fit it into 1 digit, its - 8 - 9 - a (10) - b (11) - c (12) would be a full quarter -> no suffix needed)
the normal res ones are 3 (1/16) - 6 (1/8) - 9 (3/16)
"special" ones on hi-res are 4 (1/12=30°) and 8 (1/6=60°)
idk how the condlines should be (tangential or continuous)
