Re: ogc features over orthophoto over dem

That helped Bill,
I tried to use the setRange, but it seemed to be more a tweeking around,
rather than the right thing for me. 

Instead with the Projectioncontrol things work straight.
Supposing that all the axes have the same units:

    double max = Math.max(NROWS, NCOLS);
    max = Math.max(max, NLEVS);
    double[] aspect = new double[] { NCOLS/max, NROWS/max, NLEVS/max };

And so I use the setRange for what it was ment for and the aspect is
always the proper one.
