Subject: [PATCH i-g-t 3/4] trace.pl: Bring back timeline stacking
Date: Thu, 19 Jul 2018 10:36:00 +0100	[thread overview]
Message-ID: <20180719093601.11788-4-tvrtko.ursulin@linux.intel.com> (raw)
In-Reply-To: <20180719093601.11788-1-tvrtko.ursulin@linux.intel.com>

From: Tvrtko Ursulin <tvrtko.ursulin@intel.com>

Bring back the button which expands/stacks overlapping timeline boxes.

We default to no stacking, but sometimes expanding the view can be useful,
especially with deep request pipelines.
