d7383b7b	2012-12-20T01:03:22	[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.
06174dbb	2012-12-19T22:46:27	[base] Clean up trigonometric core. * src/base/fttrrigon.c (ft_trig_pseudo_polarize): Align algorithm with `ft_trig_pseudo_rotate'.
8ac5c5c8	2012-12-15T23:33:55	[base] Fix 11-year old bug. Since the initial commit (ebe85f59) the value of FT_TRIG_SCALE has always been slightly less than the correct value, which has been given in the comment as a hexadecimal. As a result, vector lengths 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: formatting
