********************************************************************** @type: FT_Stream_OpenGzip @description: open a new stream to parse gzip-compressed font files. This is mainly used to support the compressed *.pcf.gz fonts that come with XFree86 @input: stream :: target embedding stream source :: source stream, used to @return: error code. 0 means success @note: the source stream must be opened _before_ calling this function. calling @FT_Stream_Close on the new stream will *not* call @FT_Stream_Close on the source stream. None of the stream 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 automatic 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 gzip stream from it and re-open the face with it. this function may return "FT_Err_Unimplemented" if your build of FreeType was not compiled with zlib support.
