      Description

      It can take up to 2 seconds to render an overview for a simple 150 base x 15sequence alignment (uniref50.fa)

      I have isolated the issue, not surprisingly, to OverviewPanel.updateOverviewImage(), which does many calls just to find out that a color has not changed.

      Experimenting with marking sequences as tainted.
