add 'do_rotate = .true.' to the quad interpolation namelist.
(arguably this should be set in the quad init call.) if the grid 
is anywhere close to 45 degrees, the interpolation will
introduce artifacts unless the cells are rotated to be parallel
with either the X or Y axis.  this grid is almost exactly at
45 degrees to lon/lat lines and so displays the worst artifacts
unless this flag is set in the namelist.   set it in both the
default input.nml and the template version.
