Add Support for Double-Tap Zoom Animation

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Open any map.
2. Double tap to zoom in.

What is the expected output? What do you see instead?

For better usability, I would expect to see a smooth zoom to the next native 
zoom level. Instead, 
the map "snaps" to the next zoom level, resulting in a jarring transition and 
user losing spatial 
awareness.

What version of the product are you using? On what operating system?

SVN r154, iPhone OS Simulator 2.1

Please provide any additional information below.

Not applicable?

Checked in an implementation of this feature.  Note that due to Issue 4, tile 
images
aren't always reused optimally, so even now, sometimes the map goes blank during
zoom.  You can see the effect more clearly at lower zoom levels (zoomed out 
further).

Is it correct to assume that the smooth zoom effect works as well on pich 
events and
not just double tap?

Yes, in fact the zoom effect already worked for pinches before this fix, the 
two are unrelated.

No the pinch does not work as Google map has implemented it. The pinch to 
zoom-in
should zoom at the bitmap level. When the juser then releases the pinch, the 
tiles
should load. Right now the pinch kinda work smoothly for a fraction of second 
and
then loads tiles. Not wanted behavior.

Also: The new animation feature on scroll is annoying as when you click 
anywhere on
the map: single tap, the map moves slightly. That is not wanted. 

Could Davigoli fix this? The anim should happen only when the user drags the map
