Title:
  Add Color Management to Hugin

Status in Hugin:
  Fix Released

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.
