====================================

Stamped2 Texture
Type:  Color, Filter.

This texture creates the effect of stamped plates, but unlike
Imagine's stamped texture it makes round and eliptical ones.
Apply it to a plane with the z-axis perpendicular to it.
The texture creates a checkered pattern of horizontally and
vertically oriented bumps. You can set the number of bumps
per check. If the width and length of the bumps are the same,
the bumps will be round. The bump width is relative to it's
space in the checker (when you set it to 1, the bumps will
touch), so when you want round bumps set the length to:
bump length = bump width/number of bumps.
You can also clip away the tops of the bumps as if they are
worn out. When using clipping, you can decide to remove the
clipped part of the bump (making an open bump by clipmapping;
also removing highlights and reflections).

Requester:

Size:                           Size of the checks containing x and
                                y oriented bumps.
Number of Bumps:                Number of bumps per check.
Bump width      (0..1):         Width of bump relative to it's
                                space in the check.
Bump length     (0..1):         Length of the bump.
Bump height     (0..1):         Height of the bumps.
                                Note that negative numbers will not 
                                work.
Top clip        (0..1):         Clips of the top of the bump (1 is
                                no clipping).
Stagger         (0..1):         Shift every other layer of checks.
Remove clipped  (0,1):          Clipmapping is used to clip away
                                the clipped parts of the bumps,
                                creating open bumps.
Color R/G/B:                    Color of the bumps.
