<pre>Blink blocks all the non-scalable fonts), color or not. Currently, fontconfig
treats any bitmap font as non-scalable.
As a result, Blink (used by Chrome and Opera) rejects color fonts in Google's
proposed color bitmap font format (such as Noto Color Emoji).
By treating color bitmap fonts as scalable, we can get 'Noto Color Emoji' and
other color fonts in the same format to be accepted by Blink.
An alternative is to change fontconfig to introduce 'FC_COLOR' and let clients
such as Blink accept color fonts (bitmap or not). My patch for that is

In the meantime, fontconfig on ChromeOS uses the following addition to
local.conf to treat Noto Color Emoji as scalable. See
