function print2eps(name, fig, export_options, varargin)
%PRINT2EPS Prints figures to eps with improved line styles
%
% Examples:
% print2eps filename
% print2eps(filename, fig_handle)
% print2eps(filename, fig_handle, export_options)
% print2eps(filename, fig_handle, export_options, print_options)
%
% This function saves a figure as an eps file, with two improvements over
% MATLAB's print command. First, it improves the line style, making dashed
% lines more like those on screen and giving grid lines a dotted line style.
% Secondly, it substitutes original font names back into the eps file,
% where these have been changed by MATLAB, for up to 11 different fonts.
%
%IN:
% filename - string containing the name (optionally including full or
% relative path) of the file the figure is to be saved as. A
% ".eps" extension is added if not there already. If a path is
% not specified, the figure is saved in the current directory.
% fig_handle - The handle of the figure to be saved. Default: gcf().
% export_options - array or struct of optional scalar values:
% bb_padding - Scalar value of amount of padding to add to border around
% the cropped image, in points (if >1) or percent (if <1).
% Can be negative as well as positive; Default: 0
% crop - Cropping flag. Deafult: 0
% fontswap - Whether to swap non-default fonts in figure. Default: true
% renderer - Renderer used to generate bounding-box. Default: 'opengl'
% crop_amounts - 4-element vector of crop amounts: [top,right,bottom,left]
% (available only via the struct alternative)
% print_options - Additional parameter strings to be passed to the print command

%{
% 14/11/11: Fix a MATLAB bug rendering black or white text incorrectly.
% Thanks to Mathieu Morlighem for reporting the issue and
% obtaining a fix from TMW.
% 08/12/11: Added ability to correct fonts. Several people have requested
% this at one time or another, and also pointed me to printeps
% (fex id: 7501), so thank you to them. My implementation (which
% was not inspired by printeps - I'd already had the idea for my
% approach) goes slightly further in that it allows multiple
% fonts to be swapped.
% 14/12/11: Fix bug affecting font names containing spaces. Thanks to David
% Szwer for reporting the issue.
% 25/01/12: Add a font not to be swapped. Thanks to Anna Rafferty and Adam
% Jackson for reporting the issue. Also fix a bug whereby using a
% font alias can lead to another font being swapped in.
% 10/04/12: Make the font swapping case insensitive.
% 26/10/12: Set PaperOrientation to portrait. Thanks to Michael Watts for
% reporting the issue.
% 26/10/12: Fix issue to do with swapping fonts changing other fonts and
% sizes we don't want, due to listeners. Thanks to Malcolm Hudson
% for reporting the issue.
% 22/03/13: Extend font swapping to axes labels. Thanks to Rasmus Ischebeck
% for reporting the issue.
% 23/07/13: Bug fix to font swapping. Thanks to George for reporting the
