ProbeTool cursor is off

Now that the ProbeTool is always on its using a different cursor. The point under the tip of the cursor is not the same as the point being displayed in the status area. We may need to edit cursor image so that the tip is at the center. But maybe not because the other tools work fine (overlays drag at the correct points, etc.)

Curtis, assign to whomever you think is appropriate.

The behavior seems the same as before to me—wrong, but the same. That is, the threshold falls at the center of each pixel rather than the boundaries. It is very likely a bug with JHotDrawImageCanvas.panelToImageCoords.

Dscho fixed the panelToImageCoords bug. The probe value is no longer offset from the pixel boundary. However, everything is off by one.

As of 1bb013f3, the probe is no longer wildly off, but rather always off by one data index (plus one screen pixel) in both X and Y. The bug is due to a coordinate system skew between the JHotDrawImageCanvas and DefaultImageCanvas. See also #1190 for another symptom of the same bug.
