[Development] Bringing Qt's high-dpi support to more platforms

[md at rpzdesign.com]

Morten:

Hopefully you are going to developer days in Berlin this summer.

And Hopefully you are giving a presentation that will be available on
youtube titled, "Qt Quick Developer Quick Start to developing QML Opengl
Core Graphics Code for Android and IOS on 5.3+"

I think you guys who are veterans of the foundation code could give us a
quick start instead of having to feel my way through the classes and code.

For example, I did not know how to build Qt static until I watched:

https://www.youtube.com/watch?v=chMNUzpN4pw

That video saved me HOURS of trial and error trying to understand the
process.

I would love to see what tips and tricks the experienced developers have
when arranging their build and debug environments in Windows and OSX
that you have found works back in Finland.

It would be nice to be able to start contributing code at some point
when I have a new device like the SUPER HDPI Android 8.9....

Cheers,

marco

WinRT is are using float scale factors so this will see testing there. High scale factors should not be a problem in itself, what I see from testing on desktop is that the style breaks at some point going beyond 2X.
