  [base] Reduce trigonometric algorithms.
  
  After we get within 45 degrees by means of true 90-degree rotations,
  we can remove initial 45-degree CORDIC iteration and start from
  atan(1/2) pseudorotation, reducing expansion factor thereby.
  
  * src/base/fttrigon.c (FT_TRIG_SCALE, FT_TRIG_COSCALE): Update macros.
  (ft_trig_pseudo_rotate, ft_trig_pseudo_polarize): Update.
  
  * src/tools/cordic.py: Bring up to date with trigonometric core.
  
  * docs/CHANGES: Old typo.
