if the input images are large, they don't fit on the 256x256? viewport of SingleWindowDisplay.
There are no scroll bars or zoom possibility, so the only way to see the whole image is to make the SingleWindowDisplay window itself larger.
Minimal fix here is to implement a zoom slider... and/or resize the window to try to fit the input images in,
and while we are at it, the z slider is also missing.
