Marker trail display does not work (get UnsatisfiedLinkError)

[tkuchida]

Steps to reproduce

• File -> Preview Experimental Data...
• Select Gait10dof18musc\ExperimentalData\subject01_walk.trc
• In Navigator, navigate to ExperimentalData_1 > subject01_walk.trc > Markers
• Right-click R.ASIS and select "Toggle Trail Display"

Expected result

• Trail display is toggled. Here's the result in 3.3:

Actual result

Notes

If it isn't possible to provide this functionality, the "Toggle Trail Display" item should not be displayed.

@jimmyDunne Will investigate how valuable this feature is to users.

[chrisdembia]

I use this feature whenever I am scaling a model. I use the trail to help determine a time range over which to average frames from the static pose. I choose as wide of a time frame as possible through which the markers move very little, and the trails help with this.

Thanks for the feedback @chrisdembia I'll think of a way to restore this capability. In essence we moved from making custom visualization/artifacts (which were convenient to users) to a more streamlined approach that lets components draw themselves. Will see what I can do and if it fits in 4.0.

[chrisdembia]

It's fine with me if we put this off for now.
