Fixed point for scale tool

Submitted by Jakub Friedl

Description

PROBLEM: Very usual situation when i try to align two layers (like two photos of overlapping areas): I have aligned the left part of the image, but on the other side it does not align due to different scale factor of the layers. Scale tool is the saviour. But when I scale the layer, fixed point (the point which does not move) is one of its corners, but already aligned part is somewhere inside of layer, so that if I scale the layer, I loose the alignment, unless I use handles at least at two corners, probably more than once. Time waste.

POSSIBLE ENHANCEMENT: It would be much better if I could set a fixed point in the aligned area (or anywhere else). This way i would not lose the alignment and would save a lot of time.
