Image on Plane Geometry 1
=========================

Show an image using a plane geometry. For historic reasons, image
data (usually) has the first rows representing the top of the image.
But the plane gemeometry is such that it is reversed again.

* The green dots should be at the corners that are NOT darker/brighter.
* The green dots should be on the edge of the image.
* The darker corner is in the top left.
