What is base needed for (events is latency_info, I just can't remember the dep
there)?

[tapted, 2014/11/27 02:50:33]

ScopedCAActionDisabler is in ui/base, but it can be inlined. I think this dep
was only essential while SoftwareLayer was also in ui/base, so it can be removed
if we rely on the inlining. Done.

Actually, `gn check` complains if I remove the //ui/base dependency, so I've
brought it back.
