Comment (by jrf):

 @joemcgill Thanks for getting back to me about that. Basically, I could
 only get the test to fail when Exif was disabled. Disabling GD didn't seem
 to have any effect at all.

 We may need to dig deeper into the PHP side of things there, but based on
 those tests I ran, it would appear that `getimagesize()` is always
 available, independently of GD.
 If that's the case, we could most likely simplify the
 `wp_get_image_mime()` function.
