 The dragpan control has an {{{interval}}} property. Setting this property
 to a positive value results in moving the map every {{{interval}}}
 milliseconds as opposed to on every mousemove during dragging.

 The default value for {{{interval}}} is 25 (milliseconds).

 Experiments in various browsers, including in touch devices, show that
 isn't a good value.

 As an example, open http://www.openlayers.org/dev/examples/fullScreen.html
 in FireFox, zoom a bit to see more details, and drag the map. The map
 shakes. Now open the !FireBug console, and do
 {{{
 map.controls[0].dragPan.handler.interval = 1
 }}}
 The map doesn't shake anymore.

 Setting {{{interval}}} to 0 yields good results as well in most browsers,
 but it makes the map undraggable in the native browser of the 3G iPhone,
 see #3093.

 So I'd suggest changing the default value from 25 to 1 in the
 {{{DragPan}}} prototype.

 Having sensible default values is important, so I'd suggest to include
 this change in the 2.11 release.
