* Half now implements "round to nearest even" mode.
Detailed Changes:
* Bumped DSO version number to 6.0 (Florian Kainz)
* Added new standard attributes related to color rendering with CTL
(Color Transformation Language): renderingTransform,
lookModTransform and adoptedNeutral. (Florian Kainz)
* Bug fix: for pixels with luminance near HALF_MIN, conversion from
RGB to luminance/chroma produces NaNs and infinities (Florian Kainz)
* Bug fix: excessive desaturation of small details with certain colors
after repeatedly loading and saving luminance/chroma encoded images
with B44 compression. (Florian Kainz)
* Added B44A compression, a minor variation of B44: in most cases, the
compression ratio is 2.28:1, the same as with B44, but in uniform
image areas where all pixels have the same value, the compression
ratio increases to 10.66:1. Uniform areas occur, for example, in an
image's alpha channel, which typically contains large patches that
are solid black or white, or in computer- generated images with a
black background. (Florian Kainz)
* Added flag to configure.ac to enable or disable use of large auto
arrays in the IlmImf library. Default is "enable" for Linux,
"disable" for everything else. (Darby Johnston, Florian Kainz)
* corrected version number on dso's (libtool) - now 5.0
* Separated ILMBASE_LDFLAGS and ILMBASE_LIBS so that test programs can
link with static libraries properly
* eliminated some warning messages during install (Andrew Kunz)
