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
* *.mk: Implemented `platform' target to disable auto-detection.
Added support for clipped direct rendering in the smooth renderer.
This should not break binary compatibility of existing applications.
* include/freetype/fttypes.h, include/freetype/ftimage.h: Move
definition of the FT_BBox structure from the former to the latter.
* include/freetype/ftimage.h: Add `ft_raster_flag_clip' value to
FT_Raster_Flag enumeration.
Add `clip_box' element to FT_Raster_Params structure.
* src/smooth/ftgrays.c (grays_convert_glyph): Implement it.
* src/raster/ftraster.c (ft_black_render): Test for unsupported
direct rendering before testing arguments.
