    Graphics library - match gsaves with grestores
    
    Auditing as part of the pdfi work, when the graphics library executes
    a gs_gsave() it should match it with a gs_grestore(), even in the case
    of an error.
    
    In addition, if gs_setcolorspace failed in image_PaintProc() it would
    leak the pattern enumerator. Because this is only called from PCL
    the memory is not garbage collected.
