- fixed colour space conversion matrix values


2007/06/22 - changes by Robin Davies
- Linear contrast scales relative to 1.0.
- Multi-threading support for tonemapping operations.
- Default Noise Reduction is none.
- Fixed crashes when diffraction-limited bloom radius is small.
- "Indigo" in title bars changed to "Violet".
- Well. At least the icon is the right color. Needs more work.
- Histogram re-scaled for use Ansel Adam's ten zones system, 
  rather than 17 stops of a full range image (gamma included). 
  The 17 stop range indicates where detail falls relative to 
  the blackpoint of the raw image; 10 zones seem to provide 
  a better indication of whether there's actual detail in the 
  black areas or not. Really an aesthetic decision more than 
  anything else. How black is too black?
- Range-clip before downsampling, in order to improve Reinhard
  behaviour with over-value pixels. Compute the histogram at the
  same time to allow display of overvalues in the histogram.
- Don't recompute image when saving. (Disable of menus is good enough
  to ensure that there's a valid image).
- Tweaked range of stop-related sliders.
- Major performance improvement in Diffraction-limited bloom.
- #ifdef USE_OPENMP to eliminate errors non-OpenMP compatible systems.
