[Bug 1322695] Re: Hugin won't create a panorama with "Use GPU for remapping" checked.
Note to self: Read the FAQ _before_ filling up the bug database.
http://http://wiki.panotools.org/Hugin_FAQ#GPU-stitching_.28nona.29
says that only nVidea & AMD graphics cards are supported.
Devs, is it worth adding some code so that the option is greyed out if
hugin does not detect an nVidea or AMD chip?
PS. My version is 2013.0.0.4692917e7a55
