Equalize - cancelled calculation and over-zoomed image

[davidh]

Whenever you cancel Equalize Histogram match calculation, you get an error thumbnail, which is probably OK. If you then depress both "Display Input and Preview Side by Side" add "Synchronized Scrollig" buttons, you get enormously zoomed input image.
If you rerun the calculation without stopping it, you also get the output zoomed that big.

You can put both of them right using any of the four zoom buttons in the output section of the image area (with the "Synchronized Scrolling" button pushed down). Or each of them separately with the "Synchronized Scrolling" button pushed up.

There are other scenarios but since you can always easily solve it by running the calculation without interruption, perhaps it is not a bug even though it may look a bit odd.

I fixed this for the next release (by simply removing the progress bar since it runs fairly quickly on today's computers).
