function fig2emf(h,s,p)
%FIG2EMF save a figure in windows metafile format (H,S,P)
% Usage:  (1) fig2emf      % save current figure in current folder
%         (2) fig2emf(0)   % embolden the lines before saving
%         (3) fig2emf(-2)   % embolden the lines and make width/height = 2
%         (4) fig2emf('C:/temp/<m>-<n>',0) embolden and save in C:\temp
%                                          with the m-file name and figure number
%
% Inputs: h   optional figure handle [current figure]
%         s   file name which can include <m> for the top level
%                 mfile name and <n> for figure number ['<m>_<n>']
%         p   argument for call to figbolden if required
%                 or 0 for default argument [no figbolden call]
%               [xmin ymin width height] gives the lower left corner position and the window size in pixels
%               [width height] leaves the lower left corner alone
%               [width] has a standard aspect ratio of 4:3
%               [-width/height] leaves the area unchanged but fixes the aspect ratio
