Message : [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.
