/* cH: Background information. Does this belong here? I think
* so. The background layout is clearly no property of the drawing
* routines (mg-layer), and it has nothing to do with the window
* system. Arguably it also has nothing to do with the camera, but
* would be a global property of the entire scene. OTH, it is nice
* to have cameras with different backgrounds, at least with
* different background colours.
*
* Note that this image is not scaled, it just sits at the center
* of the window (if the underlying mg-routines support a
* background image at all). The mg-layer may or may not use alpha
* blending with the background color if this is a four channel
* image.
