inkscape reads .eps files with ghostscript and that sometimes renders 
colored images with horizontal lines unless the screen is big enough (or 
the scaling is larger than the screen by a lot).  The gimp which is also 
related is the program I had to tell to use a large screen when reading 
PostScript.  inkscape is really for vector drawing not grey/color-scale 
images.
