Summary

Closes #2015

Current state of this MR: all warning should be cleaned on the fast build, I created the MR to trigger builds on all platforms and with the packaged remote modules.

Implementation Details

Fixed warning are :

• comparison of two values with different enumeration types in switch statement in mvdImageViewWidget.cxx : QSurfaceFormat and QGLFormat are in practice the same enums, but the compiler can't know that !

• !678 (merged) fixed a warning (returning temporary initializer_list does not extend the lifetime of the underlying array) but created another one (expression result unused, on Clang 6.0). The "unused result" is a dummy initalizer_list used for pack expansion. See for example this article for explanations on this trick.
