| Thought I heard something mentioned about a "once" keyword to stop image

where
| it is explained in the docs.

It's a simple thing really, just add it in to the image_map statement and
only a single instance of the image will be mapped to the <0,0,0>,<1,1,0>
space for planar (map_type 0, the default) mapping.  Doesn't do anything for
map_type 1 or 5 (I don't think so anyway) since they wrap fully around.
Cylindrical, map_type 2, however is tileable up and down along the y axis
only wrapping around the y axis.
The section called Bitmap Modifiers explains, or find through Textures/Image
maps.

Bob
