* SUMMARY
Zooming in on the Timeline should always zoom right where the cursor is.

Currently, if the Timeline shows a time range greater than the duration between the first and last record we zoom in / out the entire Timeline pinned to the start edge. This zooming behavior is rather annoying when you only want to zoom in on a particular spot and suddenly your cursor doesn't match where you zoomed.

* STEPS TO REPRODUCE
1. Inspect daringfireball.net
2. Show Timeline Tab
3. Reload => records a timeline of ~3 seconds but a timeline range of ~11s.
4. Move mouse over the 1s mark
5. Attempt to zoom in
  => expected 1s to stay where the cursor was, instead it slide over significantly

* NOTES
- Once you've zoomed in enough, if you unpin from the left edge (scroll right a bit) then zoom at a specific point it will get the desired zoom behavior.
