Artist name and Copyright info in DNG header

Revision 1863 (trunk) adds the Artist and Copyright data from the camera to the DNG header.

This uses new PARAM_xxx values defined in platform_camera.h.

Currently this is enabled for G12, SX30, SX40, IXUS310 and G1X.

If PARAM_ARTIST_NAME is defined the Artist tag is set from this value (G1X).
Otherwise if PARAM_OWNER_NAME is defined the Artist tag is set from this (G12, SX30, SX40, IXUS310).

If PARAM_COPYRIGHT is defined the Copyright tag is set from this (G1X).

This might be a dumb question, but I assume what this means is that if your camera lets you enter your name in the Canon menus,  this patch extracts that name from the camera parameters and pastes it into the EXIF header of the DNG picture ?     From what I can tell by playing with them,  neither of my cameras generically support user name entry - hence my question.   If so,  I guess a CHDK function to do this might be something to think about.

You use the Canon CameraWindow software to set these values on the camera.
With the exception of the G1X, you can't enter it through the camera menus.

Is CHDK able to write to this param? If so then it could be overwritten using textbox.
