General question about this: Will the old Qt Widgets based UI be kept 
alive meanwhile, or is it a complete switch? QML/QtDeclarative requires 
QtOpenGL, and this isn't available on Windows on ARM, unless you build Qt 
with ANGLE (which isn't trivial to cross compile). I've been talking to 
Hugo about this earlier. As desktop OpenGL drivers are what they are, it 
might also be safer to use ANGLE even for x86 platforms where OpenGL 
otherwise normally is available.

So question in TL;DR form:
- Will the old Qt gui be kept alive still?
- Will someone make an effort to cross compile ANGLE for Qt, to allow 
QML/QtDeclarative to run without desktop opengl drivers?
