In general it's the duty of the platform plugin (I assume eglfs or 
minimalegl?) to provide a native-surface which has multisampling.


The application-level API to request a multisample surface is:
http://doc-snapshot.qt-project.org/5.0/qsurfaceformat.html#setSamples

Then set the changed surfaceformat with:
http://doc-snapshot.qt-project.org/5.0/qwindow.html#setFormat


If it's still not working, you need to check what's going in the platform-
plugin
 - Is their a native egl/opengl-surface which has multisampling aviable?
 - Is the platform-plugin using it? why not?
