 At present image_get_intermediate_size() is not aware of croped images,
 infact, Images being croped is not stored in the meta data at all.

 This has caused a bug to appear in the twentyten theme which uses a post
 thumbnail of 940x198px (croped).

 If you upload an image 1024x768, and attempt to display it as 640x480,
 you'll recieve the next largest image which fits,
 image_get_intermediate_size() will return the 940x198px version. (For
 example, On the twentyten Attachment page)

 The solution i've come accross is to store if the image has been auto-
 croped in the meta data, and upon retrieval, only return croped images for
 sizes which speecify croped as OK.

 I'm attaching a POC patch, ideally, it should automatically add the list
 of custom image sizes which are cropped and test against that.
