Description

+++ This bug was initially created as a clone of Bug #941095 +++

Bug 941095 disabled subpixel antialiasing on "Retina" displays (scale = 2.0 device pixels per px or higher), as a performance optimization.

That change won't affect Windows 8 "Metro," which sets the scale to 1.4 or 1.8 on high-dpi displays (depending on the display density).  I can see noticeable differences in subpixel versus non-subpixel AA on my 1.4-dppx display, but we might be able to turn it off on 1.8-dppx displays.  (I don't have one of those to test it myself.)
