title: Android-Image-Cropper to circle
body: <p>I am trying to crop my images as a circle, for this I am using the provided library of Android-Image-Cropper - 'com.theartofdev.edmodo:android-image-cropper:2.4.+'  At the moment I am able to choose an image, the crop window appears as a circle, although it doesnt then crop to a circle but instead a square.</p>
