Subject: [PATCH 09/14] perf gtk/browser: Add support for event group view
From: Namhyung Kim <namhyung.kim@....com>
Show group members' overhead also when showing the leader's if event
group is enabled. Use macro for defining hpp functions which looks
almost identical.
Unlike other hpp backend, GTK+ needs to print dummy 0.00% output since
it's displayed with variable width fonts. So that simply skipping
with %*s trick won't work well here.
