Werner Lemberg 1658685967 Remove redundant inclusion of `ft2build.h'.
* */*: Remove `#include <ft2build.h>' where possible.

David Turner e13391333f Make macros for header file names optional.
We no longer have to take care of the 8.3 file name limit; this
allows us (a) to introduce longer, meaningful file names, and (b) to
avoid macro names in `#include' lines altogether since some
compilers (most notably Visual C++) doesn't support this properly.

*/*: Replace

   #include FOO_H

with

   #include <freetype/foo.h>

or something similar.  Also update the documentation.

Werner Lemberg 9ac9060df0 [GSoC] src/*.*: Convert block comments to `light' style.
This monster commit was created by applying Nikhil's scripts
`docconverter.py' and `markify.py' to all C header and source files,
followed up by minor manual clean-up.

No change in functionality, of course.

I used commit f7419907bc6044b9b7057f9789866426c804ba82 from
https://github.com/nikramakrishnan/freetype-docs.git.

Werner Lemberg 059bc335ce */*: Use `FT_THROW'.
This is essentially a mechanical conversion, adding inclusion of
`FT_INTERNAL_DEBUG_H' where necessary, and providing the macros for
stand-alone compiling modes of the rasterizer modules.

To convert the remaining occurrences of FT_Err_XXX and friends it is
necessary to rewrite the code.  Note, however, that it doesn't harm
if some cases are not handled since FT_THROW is a no-op.

David Turner b08fe2dc7a * massive re-formatting changes to many, many source files. I don't
want to list them all here. The operations performed were all logical
    transformations of the sources:

      - trying to convert all enums and constants to CAPITALIZED_STYLE, with
        #define definitions like

          #define  my_old_constants   MY_NEW_CONSTANT

      - big, big update of the documentation comments

    * include/freetype/freetype.h, src/base/ftobjs.c, src/smooth/ftsmooth.c,
    include/freetype/ftimage.h: adding support for LCD-optimized rendering
    though the new constants/enums:

      FT_RENDER_MODE_LCD, FT_RENDER_MODE_LCD_V
      FT_PIXEL_MODE_LCD,  FT_PIXEL_MODE_LCD_V

    this is still work in progress, don't expect everything to work correctly
    though most of the features have been implemented.

    * adding new FT_LOAD_XXX flags, used to specify both hinting and rendering
    targets:

      FT_LOAD_TARGET_NORMAL :: anti-aliased hinting & rendering
      FT_LOAD_TARGET_MONO   :: monochrome bitmaps
      FT_LOAD_TARGET_LCD    :: horizontal RGB/BGR decimated hinting & rendering
      FT_LOAD_TARGET_LCD_V  :: vertical RGB/BGR decimated hinting & rendering

    note that FT_LOAD_TARGET_NORMAL is 0, which means that the default
    behaviour of the font engine is _unchanged_.

David Turner ebe85f59c9 * 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..

Fix compiler warnings.
* src/base/ftcalc.c: Fix (potential) compiler warnings.

* src/base/ftcalc.c (FT_SqrtFixed): Corrected/optimized the 32-bit
fixed-point square root computation.  It is now used even with
64-bits integers, as it is _much_ faster than calling FT_Sqrt64 :-)
* src/base/ftbbox.c: Removed invalid "#include FT_BEZIER_H" line.
* src/base/ftbbox.c (BBox_Cubic_Check): Rewrote function to use
direct computations with 16.16 values instead of sub-divisions.  It
is now slower, but proves a point :-)
* src/raster/ftraster.c, src/smooth/ftgrays.c, src/base/ftbbox.c:
Fixed the bezier stack depths.
* src/base/ftcalc.c (FT_MulFix): Minor rounding fix.
* builds/beos: Added BeOS-specific files to the old build system
(no changes were necessary to support BeOS in the Jamfile though).
* ftconfig.h, ftoption.h: Updated "ftconfig.h" to detect 64-bit int
types on platforms where Autoconf is not available).  Also removed
FTCALC_USE_LONG_LONG and replaced it with
FT_CONFIG_OPTION_FORCE_INT64.
* builds/win32/freetype.dsp: Updated the Visual C++ project file.
Doesn't create a DLL yet.
