What happens when an unstoppable bullet hits an impenetrable wall?

A while back I wrote a document about the interactions of high-density displays and font rendering options.  I just went ahead and made it public, so, enjoy!

High-DPI, Subpixel Text Positioning, Hinting

Update (July 18, 2013): It was brought to my attention that the document had disappeared. I have no idea how that happened, but I've uploaded it again. It also means that the URL has changed. :(
