imsurf: 3D images

Plot images as 3D planes with full control over position and scale.

This function will display an image in a 3D plane with the specified position, image normal, image x direction and scale. It can display full colour and monochrome images with or without transparency.

It is a convenient wrapper for the surface function, allowing simple control of image placement.
