"RenderThickness"
• "RenderThickness" is an option for cells that determines if lines in a graphic can be drawn with varying thicknesses.
• With the setting "RenderThickness" 
False, all lines in a graphic are drawn one pixel thick, regardless of their specified thickness. It may be necessary to rerender the graphic by resizing it or choosing Rerender Graphics from the Cell menu before the change is reflected.
• The default setting is "RenderThickness" True.
