Alexei Podtelezhnikov d7383b7b86 [base] Improve trigonometric core. 
FreeType used to rely on a 24-step iteration CORDIC algorithm to
calculate trigonometric functions and rotate vectors. It turns out
that once the vector is in the right half-plane, the initial rotation
by 63 degrees is not necessary. The algorithm is perfectly capable
to converge to any angle starting from the second 45 degree rotation.
This patch removes the first rotation and makes it a 23-step CORDIC
algorithm.

* src/base/fttrigon.c (FT_TRIG_SCALE, FT_TRIG_COSCALE): Update macro
values.
(ft_trig_pseudo_rotate, ft_trig_pseudo_polarize): Remove initial
rotation.

README 

  FreeType 2.4.10
  ===============

  Please   read   the  docs/CHANGES   file,   it  contains   IMPORTANT
  INFORMATION.

  Read the files `docs/INSTALL' for installation instructions.

  See the  file `docs/LICENSE.TXT'  for the available licenses.   Note
  that we use ranges (`2008-2010') for copyright years also instead of
  listing individual years (`2008, 2009, 2010').

  The FreeType 2 API reference is located in `docs/reference'; use the
  file   `ft2-doc.html'   as   the   top  entry   point.    Additional
  documentation is available as a separate package from our sites.  Go
  to

    http://download.savannah.gnu.org/releases/freetype/

  and download one of the following files.

  Bugs
  ====

  Please report bugs  by e-mail to `freetype-devel@nongnu.org'.  Don't
  forget to  send a  detailed explanation of  the problem --  there is
  nothing  worse than  receiving a  terse message  that only  says `it
  doesn't work'.

  Alternatively, you may submit a bug report at

    https://savannah.nongnu.org/bugs/?group=freetype


  Enjoy!
