* New upstream release (SVN rev 9377)
   o Fixes many bugs concerning PDF rendering, to make the PDF printing
     workflow correctly working.
   o Fixes long-standing bugs in many drivers, like input paper tray and
     duplex options not working for the built-in PCL 4, 5, 5c, 5e, and
     6/XL drivers, PDF input not working for bjc600, bjc800, and cups
     output devices, several options not working and uninitialized
     memory with cups output device.
   o Merged nearly all patches of the Ubuntu and Debian packages upstream.
   o Fixes LP: #317810, LP: #314439, LP: #314018.

 * A plane-extraction device appears to its client to be a color-capable
25
 
 * device, like its target; but it actually extracts a single color plane
26
 
 * for rendering to yet another device, called the plane device (normally,
27
 
 * but not necessarily, a memory device).  Clients must know the pixel
28
 
 * representation in detail, since the plane is specified as a particular
29
 
 * group of bits within the pixel.
30
 
 *
31
 
 * The original purpose of plane-extraction devices is for band list
32
 
 * rendering for plane-oriented color printers.  Each per-plane rasterizing
33
 
 * pass over the band list sends the output to a plane-extraction device for
34
 
 * the plane being printed.  There is one special optimization to support
35
 
 * this: on the theory that even bands containing output for multiple bands
36
 
 * are likely to have many objects that only write white into that band, we
37
 
 * remember whether any (non-white) marks have been made on the page so far,
38
 
 * and if not, we simply skip any rendering operations that write white.
39
 
 *
40
 
 * The depth of the plane_extract device and its target are limited to 32
41
 
 * bits; the depth of each plane is limited to 8 bits.  We could raise these
42
 
 * without too much trouble if necessary, as long as each plane didn't
43
 
 * exceed 32 bits.
