  Simplify header file hierarchy. This large patch changes the header file directory layout from `include/freetype/...' to `include/...', effectively removing one level. Since the file `ft2build.h' is also located in `include' (and it stays there even after installation), all FreeType header files are now in a single directory. Applications that use (a) `freetype-config' or FreeType's `pkg-config' file to get the include directory for the compiler, and (b) the documented way for header inclusion like #include <ft2build.h> #include FT_FREETYPE_H ... don't need any change to the source code. * include/freetype/*: Move up to... * include/*: ... this directory. * builds/amiga/include/freetype/*: Move up to... * builds/amiga/include/*: ... this directory. */*: Essentially do `s@/freetype/@/@' where appropriate. * CMakeList.txt: Simplify. * builds/unix/freetype-config.in, builds/unix/freetype2.in: For `--cflags', return a single directory. * builds/unix/install.mk (install): No longer try to remove `cache' and `internal' subdirectories; instead, remove the `freetype' subdirectory.

    *   objects will be released to the heap.
    *
    *   The stream implementation is very basic and resets the decompression
    *   process each time seeking backwards is needed within the stream.
    *
    *   In certain builds of the library, gzip compression recognition is
    *   automatically handled when calling @FT_New_Face or @FT_Open_Face.
    *   This means that if no font driver is capable of handling the raw
    *   compressed file, the library will try to open a gzipped stream from
    *   it and re-open the face with it.

    *   of FreeType was not compiled with zlib support.
