Title:
  DPI Awareness/Scaling Issues (Win10)

Status in Mudlet:
  New

Bug description:
  Summary:
  Mudlet exhibits behavior associated with static size values (in pixels) in the Qt GUI widgets rather than using relative values. Additionally, the application does not specify DPI awareness such that Qt autoscales the application using the native Windows display APIs.* As such, the UI is, while usable, not properly rendered which breaks third-party UI add-ons produced by the community.

  *More info here: http://doc.qt.io/qt-5/highdpi.html

  Recommended remediation (up for discussion!):
  While an effort to convert Mudlet's QML to relative values would be the "right" fix, the autoscaling provided by Qt 5.6+ and Windows 8.1+ allow for one of the following:

     The addition of a qt.conf directive to specify an equivalent of the following (passed at runtime, instructs Windows to treat the application as non-DPI aware and to scale it automatically):
        -platform windows:dpiawareness=0

  OR

     The addition of the following property setter for Windows builds to achieve the same goal as option #1:
         QGuiApplication::setAttribute(Qt::AA_EnableHighDpiScaling);

  Steps to reproduce:
  Run the application on a High DPI Windows 10 machine such as a Microsoft Surface or 4K display with scaling enabled and set to a value other than 100%. Observe the UI scaling issues in the splash frame and Connections frame - particularly cut off text and oddly shaped fields/tiny small icons.

  I have tested the -platform windows:dpiawareness=0 solution and it's
  working with Mudlet3-iota built against Qt5.6 on Windows 10 following
  the wiki instructions. I am building and testing the second (probably
  preferable) fix.
