High DPI / scaling issues

[Gabriel-Lacatus]

Using Cropper on a Surface Book 2 currently set at 175% scaling.

A few issues related to high DPI seem to manifest:

1. The white labels of the crop size in pixels (top right corner) are overlapping the actual crop area and the bits that are overlapping will actually end up in the capture
   

2. Text scaling issues in the options window
   

3. Scaling issues with the How To and About "windows"
   

Keep up the good work, I absolutely love the tool!

Thanks. Yeah at 175% there are still some issues with scaling. I think I got most worked out at lower scales but not 175%. I didn't know how many users would see it. I'll take a look at it.
