Summary0001396: slow scene loading when ctkVTKThumbnailWidget is enabled
Description

This scene loads very slowly in slicer4:

/home/pieper/Dropbox/RonsExamples/FGBG-Test/SecondScene.mrml

After some profiling it seems a lot of time is bring spent in: ctkVTKThumbnailViewPrivate::updateBounds()

Stubbing this out (see diff below) makes the scene load very quickly!

Can we turn off this widget during scene loads?

Additional Information

Here's the part to stub out:

pieper@flint:~/slicer4/latest/Slicer4-superbuild$ (cd CTK; git diff)

My first discovery is that a polydata needs to update its entire pipeline (not just the update_extent pass) to know it's bounds. This would explain why the navigation view requires glyph computation.
What I still don't understand is why the computation would be done more than once.
