Comment (by ericlewis):

 In attachment:15311.5.diff,

 * move this logic in `image_get_intermediate_size()`, as drrobotnick had
 in his patch. This is the canonical function for attempting to get a file
 for an image size, which other functions like `image_downsize()` proxy to.
 * add a unit test.
 * give preference of cutting from the large size if it exists and is big
 enough, otherwise fallback to the original.
