Image > Zoom > Set... plugin does not always pan over center

Open boats. Use the Image > Zoom > Set... plugin. Choose center 400,400 @ 500%. Image zooms in 500% put panned to upper left corner. Trace in with debugger however and see the pan code is invoked (JHotDrawImageCanvas::syncPan()) and actually works when things are slowed down. Perhaps this is another issue with the timing of display events. (Also note that the ImageCanvas' canvasHelper generates a zoom event before the canvas actually does any zooming - could that be a problem?)

This bug is a side-effect of a more general bug: the first time a canvas zoom operation happens, it misbehaves. If you rerun the Set Zoom plugin a second time, the canvas is updated correctly. See #1290.
