Details

This is like bug 442139, only it even happens at normal line-heights.
Only happens with gfx.font_rendering.directwrite.enabled -> true.

Glyphs are snapped to pixels vertically but default line-heights are not integer numbers of pixels.
See subpixel-lineheight-1a/b in attachment 488825 [details] [diff] [review] for a reftest.
Looks like something here has fixed this

(The other possibility is that something in my patches for bug 605872, bug 600452, or bug 569770 was causing this to happen on tryserver, but I was observing the problem in nightly builds without those patches on a win7 system.)
