Description
Unwrapped alignments, when scrolled, are redrawn by method SeqCanvas.fastPaint(). This shifts the image left/right/up/down and draws on it only those positions that have come into the visible region, saving a full repaint of the whole visible region.
Wrapped alignments don't yet implement this, but could do so in a similar way.
This would improve performance of scrolling, whether vertically (in steps using the scrollbar) or especially horizontally (by continuous drag of the Overview box).
