This will apply to all CollectionItemViewCell, not just the quiz badge. This would only affect apps which configure these properties: blendedLearningImageBackgroundSize and imageBackgroundSize

@simonmitchell I feel like the white background around the badges is drawn by the CircleProgressLayer(with no progress) which I'm not sure is what we want for apps which don't use blended learning?

Can change the color to .clear here if that's desired, but it's been like that a while and nobody has mentioned anything. On the app using this the QuizBadgeTableViewCell is overriden and this white background is removed

[simonmitchell]

IIRC there was previously a .clear on the CircleProgressLayer but it looked strange because it was still rendering the shadow possibly? It's worth perhaps consolidating with PMs and designers to make sure we're doing what they expect across all clients!

I'm going to merge @simonmitchell as this PR shouldn't be breaking anything (feature enhancement) as I need to tag this up.
But I do think the white badge backgrounds above perhaps needs some checking?
