support for Qt to Hplip. What feels like a lifetime ago, my patch with the same
intention was reviewed and to be worked in a separation of Qt and hplip, which
I found reasonable at that time but drowned in all the branches I had back then.
Not forgotten though, just very low priority.
I still find Qt as a dependency for hplip unreasonable. Can we split the 
package up
as we did for Octave?

Thanks.
