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

[Tvrtko Ursulin]

From: Tvrtko Ursulin <tvrtko.ursu...@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.
