 Inspired by the image compare feature "Visual verification API" of [TestApi](https://blogs.msdn.microsoft.com/ivo_manolov/2009/04/20/introduction-to-testapi-part-3-visual-verification-apis/) this code supports comparing images by using a tolerance mask image. That tolerance mask image is a valid image by itself and can be manipulated.

-## .net Framework specific note / ImageSharp license note
-
-.net framework (an older Windows-based .NET implementation) is supported by versions 2.x.y, caused by the used dependency ImageSharp. ImageSharp dropped .net framework support starting with version 3.
-ImageSharp also made a license change. You may want to stick with 2.x.y if want to avoid that caused implications.
