It's not so easy: I, for once, don't have access to INTEGRITY to do any 
a priori evaluation of the technical feasibility of a solution.

I can test and evaluate the other platforms, though. My webgradient 
patch will improve the situation on *ALL* platforms because it removes

But it cannot go in in Qt 5 because INTEGRITY does not implement C++11's 

Is it worth it? YES.
