Optional nit: Typically, a histogram like this would be named something more
like "DirectWrite.Fonts.Ignored" or something like that... but the longer name
is fine if you prefer it.

[Ilya Sherman, 2014/08/27 00:56:30]

Is there any more general group where it would be appropriate to log these
histograms?  Maybe "DirectWrite" is appropriate; but often, using a more general
group name makes your histograms easier to find; and having fewer tiny groups
makes the dashboard easier to use.

Done.

It is close to Skia, but not part of it, would prefer to keep it separate as
it's final position could even change from renderer to browser.
