attempting to force number of quads while keeping radius interpolated along path as well.
Forcing quad count.  Displays slightly incorrectly however the mesh confirmation works
better divisions
approx t for dist along bezier
polystrips_utilities.cubic_bezier_find_closest_t_approx_distance used to solve for any given

length spacing along bezier
allow forcing of n_quads in GEdge.  Uses constant velocity asusmption
dumber but "better" f(s) = t for curve pathlength

removed old code which prevented corner snapping when gedge was force_count
tweak interger counting for radius interplation.  Is radius interpoalted from midpoint of end quads

or from edges of end quads....that is the questions.  To user it is probably not noticeable.
dynamic time step bezier evaluator adjusts time step along the curve based on closed velocity

evaluation vs numerical velocity.
