gutenprint-5.2.12

[ken@…]

According to gimp-print.sourceforge.net,5.2.12 was released on 19th January, but the downloads still point to 5.2.11 as the latest (5.2.12 is there) - I've now mailed their list about that.

Extracts from the release notes on their list on 20th January

The Ghostscript IJS driver and Foomatic data generator have been
removed.  CUPS is ubiquitous on Linux/UNIX systems, and the
Ghostscript IJS driver and Foomatic data are not needed with
CUPS.

Among many added printers, the following add new dependencies:

  Sinfonia S6145/CS2    [*1] 
  Ciaat Brava 21        [*1]

  Fujifilm ASK-300      [*2] [experimental]
  Kodak 305             [*2]               
  Mitsubishi CP-D70DW   [*2]
  Mitsubishi CP-D707DW  [*2] [experimental]
  Mitsubishi CP-D80DW   [*2]
  Mitsubishi CP-K60DW-S [*2]
        
[*1] Optimal quality requires use of an external image processing
library.  Two options are available:

* libS6145ImageProcess -- Officially supported by Sinfonia,
this library is proprietary, available only on a few platforms,
and use requires a written license from Sinfonia.

* libS6145ImageReProcess -- A reverse-engineered replacement
for the Sinfonia library, released under the terms of the GNU
GPLv3+.  Sinfonia does not support this in any way.
Unfortunately, at this time it cannot be bundled with Gutenprint.

The backend will attempt to dynamically load the library at runtime,
and will log an appropriate message if it is or is not
successful.

Note that without the library, the printer will function but
the output image quality will be quite poor.

[*2] Printing requires use of an external image processing library.
* libMitsuD70ImageReProcess -- A reverse-engineered implementation of the
 Mitsubishi algorithms, relased under the terms of the GNU GPLv3+.
Mitsubishi does not support this in any way.
Unfortunately, at this time it cannot be bundled with Gutenprint.

I suggest that we link to the new libs as external, with a note like 'only required for for XXX'. The first of these is clearly a runtime dependency, for the second I'm not sure if configure searches for it (I haven't downloaded the source yet).

I can get to this eventually.
