[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.

Don't use macro names that contain `__' [1/2]. Such macro names are reserved for both C and C++. */*: Replace macros of the form `__XXX_H__' with `XXX_H_'.

cleanups
2000-12-08 17:17:16 +01:00
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.

Extend Adobe interpreter (seac). This concludes the changes needed to add Type 1 support. * src/psaux/psintrp.c: Update includes.
