  * docs/docmaker.py: Minor improvements to reduce unwanted spaces and empty lines in output. * docs/docmaker.py: Improved script to generate table of contents and index pages. It also supports wildcards on non Unix systems. * include/freetype/*.h, include/freetype/cache/*.h: Updated comments to include section definitions/delimitations for the API Reference generator. * include/freetype/freetype.h: Moved declaration of `FT_Generic_Finalizer' and the `FT_Generic' structure to... * include/freetype/fttypes.h: here.
