[OpenLayers-Dev] animated zooming 1.1

[Emanuel Schütze]

Hi all,

many thanks for your feedback! I want to responsive to some issues:

1. zoom bar behavior bugs

Yes, I know this bug. There is also a little slider position bug (in the trunk 
code): If you drag the slider between the zoombar bottom and the area below 
the zoombar (very fast) back and forth several times, the slider moves 
upstairs. Analogical: the zoombar top.
We should be fix these bugs to have a stable zoombar (like gmaps). I would be 
grateful, if someone can do it in this month.
	
2. scale overlays

What do you think about to have an option "zoomanimated" for _every_ overlay?  
Alternative: an option for _all_ overlays.

3. scale red rectangle in overviewmap
Now, this feature is online in my new version 1.1! Look at the demo [1] and 
the ticket #442 [2]. 
Tim, I only changed a few lines in the overviewMap.js. Please review it. 
Thanks.

4. new feature: "smooth tile replace"
> Duarte: after zooming, the best effect would be to not hide the previous

Duarte, this is a good idea. I'll try it, if I finish the other features.


Any more suggestions?

Best regards,
Emanuel
