Feature request for forks: parametric save instead of raw save

[ephestione]

Use case scenario: I have a big image (picture taken with DSLR) which I do not want to resize.
I cannot load it at 100% size in this plugin both for useability and because it just doesn't cut it (10 seconds between each rotation can be frustrating, especially if you set the step to 10° instead of 90°).
So, why not use a smaller version of the image inside the JS editor, and when you click save, instead of actually saving the raw image data (of a much smaller picture, not usegul to me), return the list of steps needed to reproduce in order to obtain the edit in a server side PHP script.
For example
rotate 50° clockwise; crop rectangle from top=10.353%;left=16.783% to top=82.849%;left=57.4628%'

I can simply replicate the steps in php to get the real-size version of the rotated crop.
What say you?
