PARAMETERS
     vector   is a 2, 3, or 4 element array depending on whether you call the
              t2, t3, or t4 version of the routine.  The elements of the array
              are the s, t, r and q texture coordinates in this order.  The
              default for r is 0.  The default for q is 1.

DESCRIPTION
     t sets the current texture coordinates, s, t, r, and q.  The specified
     texture coordinates remain valid until they are replaced.  All draw modes
     share the same texture coordinates.
     Using texgen it is possible for one or both of the texture coordinates to
     be replaced by a graphics system generated value.  The coordinate or
     coordinates that are not being replaced continue to be specified by t.

     s, t, r, and q are transformed, prior to use, by the Texture matrix,
     which is modified while mmode is MTEXTU.

     Texture coordinates are ignored while texture mapping is not enabled.

NOTES
     IRIS-4D G, GT, and GTX models, and the Personal Iris, do not support
     texture mapping.  t is ignored by these machines.  Iris Indigo supports
     texture mapping except for lines and points.  Use getgde to determine
     whether texture mapping is supported.  t cannot be used while mmode is
     MSINGL.
