The "set_samples = domain_set.getSamples()" method call returns
the locations of the samples created by your call to the Linear2DSet
constructor. However, since set_samples is not used in your program,
this call is not necessary.

If you remove your call to:

  dispGMC.setPolygonMode(1);

then you will see a nice 4 x 5 texture. However, for efficiency's
sake the geometry under the texture is generally resampled to a lower
reso;ution. So when you do call dispGMC.setPolygonMode(1) you see
that lower resolution geometry. To see your natural geometry, add
the call:

  dispGMC.setTextureEnable(false);

Cheers,
Bill
