[OpenLayers-Dev] "allow pan while drawing" patch

[Cédric MOULLET]

SO GREAT  !! Thanks a lot for implementing that.
This is really powerful and usable.
Some CAD systems provide also the possibility to snap, for example, at the
intersections of lines (without having a real point) or in the middle of
circle. Usually, the cursor will change depending of the type of snapping.
But this is of course more than a nice to have.
Thanks again !
Cédric
