This gets edited into the patterns.htm file I have here immediately, thanks
Nathan.
Didn't know about the "more than 256" thing. Great, but I don't see how it
could. After all, if there's only a 256 color palette or one 8-bit plane of a
24bit image how does it apply textures to other than those specific areas of a
image then? A kind of interpolation?

| Advantages of image_pattern:
|
| 1) it is not limited to textures; it can be used directly with normals and
| pigments
|
| 2) it can provide more than 256 entries
|
| 3) it fades between entries (especially useful when you have fewer than 256)
|
| 4) it can be nested
|
| 5) it follows a more standard format (like most other patterns), unlike
| material_map, which is specialized
|
| 6) interpolation of the bitmap works better (see documentation on
| material_map for an explanation of why interpolation is not effective with
| material_maps)
