Description
Create a new IJ2 image. Now drag the lower right corner so that some white fill exists between the image and the window border. Turn on probe. Probing in the white area throws exceptions such as:

Tested its still an issue in f1ce43ef8a7217de7cf5e115ee066707ba658ab8. It only happens about once every 20 times you sweep over the image.
This code is using canvas scaling code. Changes there (for instance to fix zooming bugs) could fix this. See #628.

Easily reproducable. Open CLown. Resize window so it has a little whitespace on bottom and right. Now move mouse up and down crossing white space below image and going into/out image. Usually when crossing y = 200 (the image height) you can generate an exception. I've commented the issue a bit and left debugging code in ProbeTool source code. Apparently there is a scaling bug of some sort in the ImageCanvas/CanvasHelper code (that only seems to affect Y).

Note: it turns out it doesn't always throw exceptions. Need to repeatedly move the mouse out of the window and then into white area and then into image area. Repeatedly move around like this and occasionally an exception is thrown. Haven't yet figured out the pattern.
