/* TODO:
- Figure out 5x6, 6x5, and 6x6 prints (need 6x8 or 6x9 media!)
- Confirm 6x2" print dimensions (windows?)
- Confirm 5" media works properly
- Figure out stats/counters for non-4x6 sizes
- Job status & control (QJC, RSJ, QQA)
- Figure out occasional data transfer hang (related to FW bug?)
- Set highlight adjustment & H/V alignment from cmdline
- Figure out if driver needs to consume highlight adjustment (ie feed into gamma correction?)
- Figure out Windows spool format (probably never)
- Spool parsing
* Add additional 'reserved' fields for future use?
* Support more hdr.format variants?
* Have GP report proper modelid
- Job combining (4x6 -> 8x6, etc)
- Further performance optimizations in color conversion code
* Pre-compute then cache entire map on disk?
- Commands 8008, 8011, EST_SEHT, ESD_SHTPC, RDC_ROC, PCC_STP, CMD_EDM_*
- Test with P525, P720, P750
- Further investigation into P110S & P510 series
- Start research into P530D, X610
- Incorporate changes for CS-series card printers
- More "Matrix table" decoding work
