[ptx] link update

[Kai-Uwe Behrmann]

Hi,

would you consider to update my name with the web link from below? Even my 
contributions are currently not so directly to Hugin. The sole name is so 
nacked.

We work for CinePaint on a HDR creation plug-in, which will soon bee 
released and may be nice in cooperation with Hugin. Is Hugin ready for 
32-bit floats? Vigra should allow though.

regards,
Kai-Uwe Behrmann
