bestipple(...,'resize',false)| overrides the |'density'| option and
% plots stippling at the exact resolution of the input grid. By default,
% the grids are resized because any grid larger than about 100x100 would
% produce so many stippling dots it would black out anything under them.
% 
% |h = globestipple(...)| returns a handle of the plotted stippling
% objects.
% 
%% Example 1
% Plot high-density stippling where topography is above sea level. To do this, 
% we'll use <cdtgrid_documentation.ht
