regressions transform tool

[Timothée Giet]

Hey Scott,

Thanks, I gave a try to your last changes, but it still is a big 
usability regression to me..

As you say, " The sliders are faster, while the input allows for greater 
control.", thing is usually when needing fast transform, one would use 
handles rather than the docker, and only use dockers numerical input for 
precise transforms. (at least that's how I use it). So I don't really 
see the point in making controls in the docker faster if it makes them 
(very) restricted compared to handles. It looks prettier at first sight, 
but it is actually less usable when thinking about what they are used for.

The sliders min/max are ok for a small number of actions, but make any 
out-of-range transform much more tedious as they have to be done in 
several steps, and doing boring calculations to split a big transform in 
several ones, or rely on imprecise transform (which is not an option 
most of the time when I need precise transforms).
Also changing position to relative values instead of absolute makes it 
not really possible anymore to place directly a selection at a precise 
pixel position in the picture.

I forward the discussion on the mailing list, so we can have more 
opinions on this problem.
(to the list people: read previous emails below for context ;) )
