[vtkusers] imageViewer size within QVTKWidget

[Simon ESNEAULT]

Hello Community,

I'm trying to debug this problem with QVTKWidget on retina display (without
success for now)
Just wanted to share that there is a way to simulate an HiDPI display and
to reproduce this bug on an OSX system with a "normal" screen
- Launch this command in a terminal : sudo defaults write
/Library/Preferences/com.apple.windowserver.plist DisplayResolutionEnabled
-bool true
- Log out/ log in
- Go to preference -> display and you should have one additional resolution
available looking like : 960x540 (HiDPI)

And now launch a program with a QVTKWidget, Qt5, VTK 6.1 and HiDPI enabled
(need <key>NSHighResolutionCapable</key><true/> in the info.plist inside
the .app) and the VTK viewport should fill only the bottom left quarter of
the QVTKWidget.

If any Qt/VTK skilled debugger has a hint on how to solve that particular
problem ...
Thanks,
Simon
