[Gimp-user] IImprovements to unified transform

[programmer_ceds <forums gimpusers com>]

The functionality displayed in the video is impressive but, if I understand it
correctly, the Readjust button repositions all of the handles (including the
centre of rotation) within the current visible area.

This doesn't get around the pain of having to zoom in to see the results of a
transformation and then zoom back out to continue dragging the handles or
rotating (without changing the centre of rotation).

What would be really useful is if the effects of the UT tool were visible on all
of the opened views of the image - the UT tool could then be used on a zoomed
out view whilst one or more zoomed in windows could be used to check the effect
in detail.

Would it be possible to include an option for doing this whilst you are working
on this section of the code?
