Chromatic Aberration

Hi,
Experienced HDR makers know chromatic aberration is exaggerated when the saturation is increased, which many do.
The good news is that dcraw (and other free RAW programs) now support chromatic aberration correction.
Since Picturenaut uses dcraw for raw processing, can a feature be introduced to pass through the command to dcraw.
The dcraw syntax is dcraw -C red blue
More here: http://www.cybercom.net/~dcoffin/dcraw/dcraw.1.html and here: http://wiki.panotools.org/Tca_correct
Other dcraw commands could be useful to pass through, such as specifying a dark frame.
