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
