Change summary:

• Re-worked gamut mapping to improve perceptual intent saturation levels, as well as
  improve highlight and shadow contrast. Added fine tuning to improve both smoothness
  and the precision with which the source is mapped to the destination.
• Added illumread, which allows measuring an illuminant and estimating its UV content,
  for better accuracy with FWA compensation.
• Use a modified/forked version of libusb V1.0, that supports Win2K (libusb0.sys) back
  end by default. Supports 64 but MSWin using a combination of WinUSB.sys and
  ptlibusb0.sys.
  [The HCFR does not work on Win 64 bit though, due to its buggy USB implementation.]
  NOTE that the included version of Libusb V1 has been carefully tested with all
  supported instruments on all supported platforms, and includes many bug fixes
  needed for correct functioning. While bug fixes have been fed upstream, not all
  have been adopted. In particular there is a nasty race condition that
  has not, and may never be fixed upstream, as well as missing critical functionality
  (clearep()).
• Modified colprof -p to allow different abstract profiles to be applied for each
  intent.
• Added -I option (imitation) to printcal, so that an existing devices response can
  be set as a target.
• Increase target/ofps.c vertex intersection retries from 10 to 40 to give it a
  better chance of working with difficult profiles.
• Fixed bug in plot that shows up on XP+, where the window isn’t dismissed by
  the first keystroke, but only after it has been moved or resized.
• Changed CMYK black point to be natural, rather than the darkest point in the
  same direction and K only. This may wreck K only to black point matching, but
  it will stop printers with funny colored K ink from messing up the black point.
• Make Lacie Blue Eye colorimeter appear as an i1display.
• Improved i1pro matching to Original Manufacturers Driver (see doc/i1proDriver.html).
• Improved i1pro/ColorMunki patch recognition for better uniformity.
• Fixed bug in ColorMunki driver scan mode calibration when instrument is
  more sensitive than usual.
• Added EV calculation to spotread -a
