- * TTBD:
- *
- * Add a "warning mode" to file reading, in which file format
- * errors are ignored where possible, rather than generating
- * a fatal error (see ICM_STRICT #define).
- *
- * NameColor Dump doesn't handle device space correctly -
- * should use appropriate interpretation in case device is Lab etc.
- *
- * Should recognise & honour unicode 0xFFFE endian marker.
- * Should generate it on writing too ?
- *
- * Add support for copying tags from one icc to another.
- *
- * Should fix all write_number failure errors to indicate failed value.
- * (Partially implemented - need to check all write_number functions)
- *
- * Make write fail error messages be specific on which element failed.
- *
- * Should add named color space lookup function support.
- *
- * Would be nice to add generic ability to add new tag type handling,
- * so that the base library doesn't need to be modified (ie. VideoCardGamma) ?
- *
- * Need to add DeviceSettings and OutputResponse tags to bring up to
- * ICC.1:1998-09 [started but not complete]
