<P>
These formats are most often used for viewing matrices and vectors.
<P>
If a format (for example PETSC_VIEWER_DRAW_CONTOUR) was applied to a viewer
where it didn't apply (<A HREF="../Viewer/PETSC_VIEWER_STDOUT_WORLD.html#PETSC_VIEWER_STDOUT_WORLD">PETSC_VIEWER_STDOUT_WORLD</A>) it cause the default behavior
for that viewer to be used.
