Auto-orient effect support

Nice!

Can you provide a regular unified git diff, please?

The git diff one is the right one. :) This applies to all patches on drupal.org. Btw, you might be interested in reading the Configuring Git handbook page (and possibly related pages). :)

That's not meant to confuse you though - the .git.diff patch from #2 is fine. :) (That said, we commonly use .patch as file extension ;))

This looks pretty good already and I think we're close. I only have some smaller nitpicks:

Hm — "Auto orient" is not really a term or phrase.

While "Auto-orient" would probably be more correct, that would still be very technical, and I think that the labels are more focused on user interaction.

How about one of these?

1) Automatically correct orientation
2) Fix orientation
3) Adjust orientation

What do you think?

I think I'd opt for the last one, but you definitely have more experience with this effect :)

Would be great if you could provide a final patch that incorporates the tweaks outlined in #3.

Thanks for reporting, reviewing, and testing! Committed to 7.x-1.x.

A new development snapshot will be available within the next 12 hours. This improvement will be available in the next official release.
