  [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.

     * @Function:
     *   Get_Kerning
     *
     * @Description:
     *   A driver method used to return the kerning vector between two
     *   glyphs of the same face.
     *
     * @Input:
     *   face ::
     *     A handle to the source face object.
     *
     *   left_glyph ::
     *     The index of the left glyph in the kern pair.
     *
     *   right_glyph ::
     *     The index of the right glyph in the kern pair.
     *
     * @Output:
     *   kerning ::
     *     The kerning vector.  This is in font units for
     *     scalable formats, and in pixels for fixed-sizes
     *     formats.
     *
     * @Return:
     *   FreeType error code.  0 means success.
     *
     * @Note:
     *   Only horizontal layouts (left-to-right & right-to-left) are
     *   supported by this function.  Other layouts, or more sophisticated
     *   kernings are out of scope of this method (the basic driver
     *   interface is meant to be simple).
     *
     *   They can be implemented by format-specific interfaces.
