Hi list,

here is my first version of the animated zooming feature:
http://dev.openlayers.org/sandbox/emanuel/animatedZooming/demo.html

You'll find my patch file in the ticket #442:
http://trac.openlayers.org/ticket/442

Features in the current version:
- zooming with the zoomslider -> scale all tiles by shrinking/enlarging 
- scale all active/visible layers (what do you think about the performance?)
- simple zoomOut (gets a white frame)

Features for the next versions:
- preloading specific tiles of lower zoomlevels to prevent the white frame 
during zoomOut
- scale the red rectangle in the overviewmap 
- animated zooming with +/- buttons like the demo [1] of animatedPanning 
(#110) 
- animated zooming with mousewheel 
- animated zooming with +/- keys

Do you have more ideas/suggestions?
Please test the demo and tell me what you think about it! Thanks.


Best regards,
Emanuel

PS: I have to finish my implementation by the end of february.
