Quick tests did not show any glitches.

Speedwise:
going from one image to the next (8MP jpegs)
the last 11% of the progress-bar are now really fast
(I think that this was the part where the image was actually built
on-screen).

However, I think it would be nice if the time for "Loading ..."
would be shorter (even on a Core 2 Duo with 2 GHz and 2 GB RAM
it is about 1s to go from one image to the next).
This is also true when going back-and-forth between two images
(wasn't there some caching supposed to be active?)

But maybe this is because I compiled from svn
(eg., would an --enable-final during configure possibly speed up things?)

And I thought it was *those* often mentioned jpeg artefacts which
I saw and did not bother reporting this ;-)
