Transformation geometry resize : display preview ...

[pierrelabreche]

• Zooming and panning should remain invariant when changing the sharpening
• Zooming and panning should be showing the same image area when switching from Display input to display preview
• Should sharpening have controls for halo limits ?

The sharpening slider in Resize has a very minimal effect of the result -- it tweaks the resampling kernal slightly.

Synchronized scrolling is only supported in transformations that always preserve the image dimensions.
