Add MaterialImageBundle

          Great suggestion, I agree with you there, I wasn't aware of `ContentSize`

I'd like to get this PR done and would be happy to take on the MaterialImageBundle as a followup once it is ready

As commented there: couldn’t the image handle and its size and such be part of a material type?
