Youker does really funky font scale changes in Unity HiDPI mode

[Kevin Shenk]

When HiDPI scaling is enabled in Unity, Youker Assistant always seems to resize the fonts upon startup.

For example, with scale set to 0.875, my com.canonical.Unity.Interface.text-scale-factor was set to 0.88. When Youker is started, the value momentarily jumps to 0.88000000000000004, then resets to 0.69999999999999996. If closed and restarted, the value jumps to 0.5.

If the HDPI scale is set any value above 1, the font scale actually increases when starting Youker. If HiDPI scale is turned off (set to 1), the text-scale-factor is completely unaffected by Youker.

I have a feeling that this bug may actually be located at a lower level then Youker, as one of my desktops does random text-scale-factor resizes upon user login when HiDPI scaling is enabled, even though Youker is not installed. I just haven't been able to track down any consistant factors why, and Youker triggers the bug very consistantly.
