Dive video: paint duration-bar above thumbnail in profile plot

Paint a rectangle on top of thumbnails indicating the run-time
of the video.

Use the z=100.0-101.0 range for painting the thumbnails, whereby
the z-value increases uniformly from first to last thumbnail
(sorted by timestamp). The duration-bars are placed at z-values
midway between those of the thumbnails.
