[Intel-gfx] [PATCH i-g-t 03/11] trace.pl: Scale timeline for better precision

From: Tvrtko Ursulin <tvrtko.ursulin at intel.com>
vis library has a limited precision compared to our trace data which
prevents zooming into the timeline and seeing the fine detail.
Scale the HTML view by a thousand to work around it.
