Duplicate command fails to preserve overlay coordinates relative to image data coordinates.

[Michael Ellis]

The Duplicate command when used with a region of interest to create a copy of a portion of an image, fails to translate the overlay.

For example:

- Open the "Clown"  sample image,
- Use the Oval ROI tool to draw an oval around the clown's right eye. (right to you, not the clown - not that it really matters!)
- Add this oval to the overlay using the "Add Selection" tool.
- Create a rectangular ROI that is larger than and  completely encloses the overlay oval.
- Use the Duplicate command to create a copy of the selected ROI of the image.

The selected portion of the image is duplicated but the oval in the overlay now occupies a different position relative to the clown's eye.

This script the demonstrates the problem:

run("Clown (14K)");
makeOval(147, 62, 90, 44);
run("Add Selection...", "stroke=blue width=2 fill=none");
makeRectangle(111, 34, 166, 113);
run("Duplicate...", "title=clown-1.jpg");


The overlay is duplicated but its position relative to the image is not preserved.

Any thoughts? Is this a bug or a feature that other things rely on?

This is a bug that is fixed in the 1.44k daily build.
