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 9159128a92 Silence gcc 7's fall-through warnings in `switch' blocks.
Instead of an intentionally missing `break' statement there must be a
comment line containing `fall through' (and nothing else) right before the
next `case' statement.

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.

Shao Yu Zhang f04d81751a [sfnt] Preliminary support of coloured layer outlines.
This commit enables OpenType's COLR/CPAL table handling; a typical
application are color emojis that can be scaled to any size.

If the color palette does not exist or is invalid, the rendering
step rasterizes the outline instead.  The current implementation
assumes that the foreground is black.

Enable this by defining option TT_CONFIG_OPTION_COLOR_LAYERS.

There are still some issues with metrics; additionally, an API to
fetch color layers is missing.
