[OSM-dev] Slippy map and zoom

[Lars Aronsson]

When I use the scroll wheel to zoom in and out of the slippy map, 
whether on www.openstreetmap.org, maps.yahoo.com, or 
maps.google.com, the screen goes blank for a short while before 
the tiles of the new zoom level arrive.  At Google Maps, some red 
corners move about showing whether I'm zooming in or out.

Would it be possible, in JavaScript, to show the existing tiles, 
rescaled by the browser, until the new tiles arrive?

If this was possible, I guess the browser could also emulate finer 
grades (half-levels) of zooming.  It would make for a less bumpy 
user experience.
