Re: [Texmacs-dev] Version 1.99.14

[Massimiliano Gubinelli]

Ok, I understood the problem. Qt clipboard cannot manage the mime type 
"application/pdf" correctly, so it converts it to "application/x-qt-image" and 
apparently does a lousy job with the resolution. There is nothing one can then 
do on the TeXmacs side...
