Fix bounding box in MATLAB exported encapsulated postscript (.eps) files

Tweak bounding box (excess space) from matlab exported encapsulated postscript files (.eps)

I found that the bounding box on matlab exported eps files was too large on the left and right side. This script just reads in the .eps file and reduces the bbox.

% matlab seems to compute a bounding box on eps files which is too
% large in the x-direction
%
% this script fixes the bounding box.
% it is 99% stolen from fixeps.m, located here:
% http://www.mathworks.com/matlabcentral/fileexchange/loadFile.do?objectId=4818&objectType=file
% the only change is that this actually changes the bbox numbers
% seriously, the only change is the addition of lines 19,20,31,32
%
% boundingbox has form of:
% %%BoundingBox: x1 y1 x2 y2
% where (x1,y1) is lower-left and (x2,y2) is upper-right
%
% matlab computes x1 too small and x2 too large
