| SE_IMAGWRAP_CLAMP |
Texture coordinates in the image space are clamped to the
value range [0.0, 1.0]. Negative texture coordinate values
are mapped to 0.0, while values greater than 1.0 are mapped
to 1.0.
EXAMPLES:
1. The following texture coordinates all map to
texture coordinate {0.0, 0.0}:
{-1, 0} {-5, -5} {0, -50}
2. The following texture coordinates all map to
texture coordinate {1.0, 0.0}:
{1, -1} {5, -5} {5, -50}

| SE_IMAGWRAP_REPEAT | The image space is considered to extend to infinity; it is repeated in a tiled manner. |
