Comment (by ericlewis):

 markoheijnen and drrobotnik's patches are great, and apply the problem at
 the underlying API level. This is more helpful than what I did in
 attachment:15311.2.diff, to generate the image for a whitelisted image URL
 request. I wonder if the latter has utility - my guess is no.

 I've collated both of the two patches, adding documentation and preferring
 internal functions where we can.

 I've also juggled the logic a bit, giving `image_get_intermediate_size()`
 a chance, then consider generating an image on the fly, then falling back
 to original.
