Under normal circumstances we are usually close to the desired range

[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.

Since the initial commit (ebe85f59) the value of FT_TRIG_SCALE has
always been slightly less than the correct value, which has been

were underestimated and rotated vectors were shortened.

* include/freetype/fttrigon.h, src/base/fttrigon.c, src/base/ftbase.c,
src/base/Jamfile, src/base/rules.mk: adding trigonometric functions
to the core API (using Cordic algorithms).
* builds/top_level.mk, builds/newline, builds/detect.mk: fixed problems
with Make on Windows 2000, as well as problems when "make distclean" is
invoked on a non-Unix platform when there is no "config.mk" in the
current directory..
* builds/freetype.mk: fixed a problem with object deletions under
Dos/Windows/OS/2 systems
* src/tools: added new directory to hold tools and test programs
moved docmaker.py, glnames.py to it..
* src/tools/docmaker.py: improved the script to add the current date
at the footer of each web page (useful to distinguish between versions)
* Jamfile: fixed incorrect HDRMACRO argument.
* TODO: removed the cubic arc bbox computation note, since it has been
fixed recently..
* include/freetype/t1tables.h, include/freetype/config/ftoption.h:
