FS#634 - Support Panorama sizes on EK8810

EK8810 in the APEX system supports:

8x14, 8x16, 8x18, 8x20, 8x22, 8x24, 8x32, and 8x36 print sizes.

(8x32, and 8x36 are presumably only available on 8x12 media)

Figure out how to make this happen. And what needs to be done on the overlapping areas.

To make progress, I will need access to documentation and/or USB sniffs from an APEX system. Neither is likely.

Kodak just released a firmware update and windows driver that supports.. 8x14, 8x16, 8x20, 8x24, 8x32, 8x36 sizes.

ok, the windows driver just sends a single large print (eg 8x36 == 2624*10824) and the firmware presumably does the rest!

It's implemented, and pushed to gutenprint. Now all we need is someone to actually _test_ this stuff!

It's possible the driver needs to chop things up behind the scenes.  There's also a command that a now-deleted sniff has that presumably is used to check that it's okay to start printing a panorama.

Driver is confirmed to chop things up behind the scenes.  Don't know how panorama is specified over-the-wire.

Reworked. Backend now splits up the single large "panel" into smaller overlapping panels. Fading/blending of the overlapping regions isn't implemented yet.  Do not know what has to change in the command header for each panel.

Pano splits are plubmed into backend now.  However, we still don't know how to make the printer do the split.

Uncovered a pile of bugs in the sinfonia_pano_split code; fixed them up.  But no way to test still.
