+Chrome OS font rendering settings are specified using Fontconfig. If your
+system's configuration doesn't match Chrome OS's (which vary for different
+devices), fonts may be rendered with different subpixel rendering, subpixel
+positioning, or hinting settings. This may affect font metrics.
+
+Chrome OS's settings are stored in the media-libs/fontconfig package, which is
+at src/third_party/chromiumos-overlay/media-libs/fontconfig in a Chrome OS
+checkout. You can configure your system to match Chrome OS's defaults by
+creating or editing a ~/.fonts.conf file:
+
+<?xml version="1.0"?>
+<!DOCTYPE fontconfig SYSTEM "fonts.dtd">
+<fontconfig>
+  <match target="font">
+    <edit name="antialias" mode="assign"><bool>true</bool></edit>
+    <edit name="autohint" mode="assign"><bool>true</bool></edit>
+    <edit name="hinting" mode="assign"><bool>true</bool></edit>
+    <edit name="hintstyle" mode="assign"><const>hintslight</const></edit>
+    <edit name="rgba" mode="assign"><const>rgb</const></edit>
+  </match>
+</fontconfig>
+
+To load additional per-font configs (and assuming you have Chrome OS checked
+out), add the following immediately before the "</fontconfig>" line:
+
+  <include ignore_missing="yes">/path/to/src/third_party/chromiumos-overlay/media-libs/fontconfig/files/local.conf</include>
