This is a panel that contains an OffsetCanvas, a Label, and two Scrollbars.
When the OffsetCanvas is resized, the Scrollars will adjust so
that the image can be completely viewed, and no more (you can
scroll just to the edge of the image). If the OffsetCanvas is
larger than the image, the image gets centered inside it.
the Label displays the current cursor location in the OffsetCanvas, relative
to the contents of the OffsetCanvas.
