in. Transform.axisBounds allows an offset to be applied to voxel
coordinates. New method, Image.axisMapping, which basically wraps

anywhere. I think I wrote it before writing the axisBounds function.

displayed with the bottom left voxel at display location (0, 0). This
means that calculating voxel location from display coordinates is
different depending on the space that the image is displayed in. I think
I've figured out the location panel, but need to double check, and need
to take a closer look at the editor.

I've decided that it should be unnecessary.
