%
%  Export drawing to different formats: PostScript, JPEG, PDF, PNG
%
% Inputs:
%  filename      = name of output image (should end in .eps, .jpg, .pdf, or .png)
%  output_coords = [default: 0] Also output tab-separated file with:
%
%                    x y chain segid resnum name
%
%            for each residue/ligand/protein in the drawing.
%            Name will be filename.coords.txt.
