   New snapshot available, hopefully flicker free.

   | 2) Thumbnail display is still very slow, with a lot of flickering.  I
   |    sometimes see a bunch of thumbnails drawn, and then sometimes they
   |    get momentarily erased and redrawn, when scrolling.  This is very
   |    distracting and rather time consuming.

   I'm sure I've managed to get it slower with my latest checkin, but
   I can't do miracles, you know.

   However, it should now be flicker free, let me know if you agree.

Much better, although a few comments:

1) Paging/scrolling *down* is very fast.  Paging or scrolling up, or
   seeking to a random spot, is much slower (very slow in the case of
   scrolling up).  I suspect that this is a design decision on your
   part, and probably not an unreasonable one, to keep trying to read
   ahead.

2) Another issue that I've observed, that I think I also observed with
   earlier versions but have not been able to reproduce reliably, is
   that if I seek with the mouse using the middle button on the
   scrollbar and then use the pageup/pagedown keys, the
   pageup/pagedown positions me relative to the last position I was
   at.

   For example: if I page down twice, that leaves me at page 2 (let's
   just call it that, even though there's no concept of pages).  Let's
   say I now use the mouse to position me at page 50.  If I now hit
   the pagedown key, it leaves me at page 3.
