Gantt View Marcus Bains line overlaps into swimlane label area

[charlesh88]

Summary

When the Time Conductor is in Fixed Time mode, the Marcus Bains (MB) line (aka "the now line") can overlap into the swimlane "label" area:

This occurs in Plan, Gantt and Time Strip views.

Expected vs Current Behavior

The MB line should not be shown when it is outside the time context of the view. This works as expected when manually entering start and end times in the Time Conductor's popup, but doesn't when "panning" the time frame using alt-drag on the Conductor's ticks area.

Steps to Reproduce

1. Set the Time Conductor to Real-Time mode, and navigate to any view of a plan: Plan, Gantt or Time Strip.
2. Set the Time Conductor such that it uses 1 hour offsets into both the past and the future:
   
3. Verify that the MB line appears in the view, in the middle of the time context area of the view:
   
4. Switch the Time Conductor to Fixed Time mode. The view itself should look the same:
   
5. Press and hold the alt key and click-drag to the left on the ticks area of the Time Conductor to pan back into the past. Use a small motion to avoid having the MB line move completely out of the view. If you didn't quite get the line into the swimlane labels area, keep repeating small moves until you do:
