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

[Andreas Hocevar]

Hi Eric,

thanks for your efforts. My only concern is that adding vertices on mouseup instead of mousedown negatively affects the user experience when a Snapping control is used. This is because the user doesn't see any more where the vertex is going to be snapped to.

At this point, I have no idea how to solve this.

Andreas.
