See bug 73884 When drawing solid outlines we use the Pen of the Device Context. Currently only Windows supports the Pen being in an invert-mode, so only Windows can do the invert outlines. Mac and Linux need this as well (and OS2 and BeOS and whatever else is out there, by extension). Note: dotted and dashed outlines use DrawRect and that uses InvertRect for doing the invert, so it works on all first-tier platforms.
