Title:
  Add Color Management to Hugin

Status in Hugin - Panorama Tools GUI:
  New

Bug description:
  (Note: I'm also posting this to the Hugin gmail group)

I've been playing with RPP 
(http://www.raw-photo-processor.com/RPP/Overview.html) for RAW conversion 
preliminary to generating panoramas with Hugin (most recently Harry van der 
Wolf's OSX build of 2010.4.0-beta2); and running into problems with the color 
space.

RPP generates TIFF files in the BetaRGB color space; and using these files 
directly in Hugin I find two problems:

1) The panomatic control point generator barfs on these - Exception Type:  
EXC_CRASH (SIGABRT) in the crash logs ( I can provide details if you like).  I 
can generate control points manually, or with autopano-sift; and the alignment 
and distortion optimization runs as expected.

2) The expoure optimization generally leads to absurd results; usually a strong 
horizontal exposure gradient, and if I try white balance optimization then the  
resulting panorama reminds my of my experiments in recreational pharmacology 
many decades ago.

I can work around this by converting the files from BetaRGB to ProPhoto (e.g. 
in Photoshop, that being what I'm most familiar with), after which Hugin 
handles them with no problems.  But this is a pain when I have hundreds of 
images to deal with.

It's not clear if these are bugs or just a case of input that Hugin (or its 
components) weren't designed to handle; outside of RPP I haven't run across 
BetaRGB anywhere else.  And I don't know the underlying math well enough to 
know whether adding support for this is a trivial fix or a major overhaul.

If this is a bug, I can provide lots of detail; if it's a missing feature, 
please consider this a feature request.
