Multi-touch [ Devel Digest, Vol 98, Issue 6]

[forster at ozonline.com.au]

Additional speculation: testers may be also using the wrong gestures  
for this version of Android. On my Galaxy S3 smartphone, I do not need  
to triple tap to enable zoom and I can pan with one finger rather than  
two.

These two speculations aside, the zooming seems unresponsive at times,  
even when I am careful not to cross on X or Y
