"I remember considering both possibilities when implementing this (constrain to original vs. current ratio), and there was a strong reason for going with the original ratio. I can't remember why at this point, but the code for that stuff (the Move* tools and especially their history actions) is easily the most complex in the whole application. So I must have had a good reason. I'll revisit it at some point though and see if it still makes sense to do it this way, or if there's some possible workaround."
