Goes wrong for small images

I posted a bug on Github but just adding this here too in case you missed it.

If I upload say a 100×100 image, and my theme is saying to use the “large” size, which in the Media settings is set to 500×500 then the returned image is the thumbnail cropped and scaled really badly to the size.

I believe WordPress default behaviour is to just server up the largest file? That would be preferable, or even the image scaled up but NOT the thumbnail scaled.
