Small delay in Viewer when switching images (Cache, no HQ)

[Olivier_G]

With Options>View>Misc>'Keep current image in cache' and 'Read one image ahead' = ON.
...and Options>View>no HQ at all.

Open an image A in Viewer (and wait for next image B to be cached)
-> if you move slowly between A and B, switching is immediate.
-> but if you move quickly between A and B, there is a small delay before switching (it shouldn't as Caching in on interruptible thread).

Note: it is not exactly as in this topic as the delay happens here in Low quality and not in the other topic + Viewer and Browser have different mechanisms.

Please postpone, the view mode cache must be rewrited in next release!

Doh... ...oh well, discussing Cache for the next version will be interesting, though...
