Update to 8.64.  Changes include:

- Improvements to overprint and spot color support in documents with
  transparency, improvements to PDF and PS output, proper handling of
  PDF-specific text rendering modes and support for reading
  AES-encrypted PDF documents.

- Improved handling of CJK text, especially in vertical writing modes.

- Improved memory footprint processing some files at high resolution.

- The handling of color spaces has been moved from PostScript code to
  C.

- A number of the included printer drivers and cups wrappers have been
  updated to support a PDF-based workflow. Also fixed are several
  long-standing bugs in the pcl drivers with respect to duplex,
  resolution and paper tray selection.
