ui: Add 100ns margin to both sides of trace The first and last events in the trace are often hard to click on since scrolling is bound by these timestamps. This issue is especially bad when the trace contains a handful of events (as is often the case with heap profiles) since the user is more likely to want to click on an 'edge' event. This introduces a fixed time margin to both ends of the trace allowing the user to zoom in a select 'edge' events. Bug: 178383244 Change-Id: I7ef7aa9f77cd0d0c6c80117b8bdd69666277740e
