[ptx] hugin 0.6 released

[Pablo d'Angelo]

Hello,

I have just released hugin 0.6.

Source code and windows binaries are available from 
http://hugin.sf.net/download.

Here is an incomplete list of the changes:
* updated vigra to version 1.4. All sourcecode of hugin is now
   released under approved open source licences. This means there
   is no problem with including hugin in debian and ubuntu anymore.
* Copy ICC profiles from input images to output
* Added vignetting correction and brighness correction
   during stitching.
   Vignetting can be corrected by addition or division.
   The correction can be done with a flatfield image or an
   radial polynomial
* Functionality to estimate the vignetting polynomial
   directly from the overlapping images. This is an experimental feature.
* Multithreaded remapping. hugin and nona fully utilize multiple
   CPUs or multi core CPUs during preview generation and stitching
* support for dcraw 16 bit .ppm files
* Disabled PTOptimizer progress display on OSX. This should fix
   the crashes some people have experienced.
* New command line tool (fulla), for distortion, TCA and vignetting correction.
   Can use PTLens database (old format only).
* reorganized GUI layout.
* Czech translation added

This release works best with panotools version 2.8.4. Please also update 
your panotools version if you are using a previous version.

As always the windows packages include panotools (with PTmender, PTblender, 
PTtiff2psd, PTuncrop) and enblend, so no further downloads are needed to get 
started.

ciao
