// internal: can set bevel to true and get non-garbage result
// bevel is always set by thread depth
// acme takes tpi
// square threads are at angle 0
// added generic_threaded_{rod,nut}
// eliminated metric_trapezoidal_*
// cleaned up matrices some in generic_threaded_rod
// threaded_rod can produce spec-true ISO/UTS profile with a triplet input for the diameter.
// Added bevel1 and bevel2 to all modules. Made default uniformly false for every case instead of
// sometimes true, sometimes false
// Profiles that go over zero are not clipped, and bevels are based on actual profile top, not nominal
// When bevel is given to nuts it bevels the outside of the nut by thread depth
// higbee looks best with quincunx, but it's more expensive. Select quincunx when higbee is used, min_edge otherwise
// Current code uses difference to remove excess length in the rod. This gives faster renders at the cost
// of more complex code and green top/bottom surfaces.
// Changed slop to 4 * $slop. I got good results printing with $slop=0.05 with this setting.
// Don't generate excess threads when starts>1, and don't force threads to be even
//
// Fixed higbee in spiral_sweep for properly centered scaling and for staying on the internal/external base of threads
// Fixed bug in spiral_sweep where two segments were missing if higbee is zero
// Fixed faceting bugs in spiral_sweep where segments weren't aligned with requested number of segments, and higbee
// would pull away from the cylinder by using a higher count and following a true circle
