It drives me crazy too because it's not clear how you turn off the 'revert 
to original' feature permanently, for example if you want to repurpose the 
image entirely and completely lose the original size. I mean, if I'd 
altered the shape of an image in a graphics package, I wouldn't expect the 
'original size' to haunt me forever, would I? I don't see an original size 
as a 'natural' size; it's just what I started with, neither more nor less. 
As I see it, a resized image is a new image, and the idea that the system 
has a mysterious way of retaining its history is eccentric to say the 
least. What if I duplicated it seven times and make each of the dupes a 
different size, and then made each of the dupes part of a shape-changing 
animation, moving between the new size of the dupe and some other size 
dictated by the animation (this is an extension of a real case)? The way 
things are now, I'd have to use an external package to do all these 
transformations.

I'd like it so if I wanted the history, I could save it myself - otherwise 
transformations should stay transformed. BTW I am not convinced that the 
lockLoc feature works completely in all situations - at least I've had some 
problems with editing groups (by script) which contain resized images. I 
admit that these were too obscure to chase down into proper Bugzilla reports.

Just my 2 eurocents as ever
