I suppose it's a "c" plug-in, so unreadable for me.
Does someone who reads "c" (assuming the source is available) understand "which" rotation will it do by default? 0-90 to 90-180? or what?

I assume this is the rotation you see when you start the dialog.

An equivalent script could be writable in Python using Numpy. All of this is scalar operations applied to matrices.
