| * @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. |
