[OpenLayers-Dev] Re: 2.11 SketchStarted

[Xavier Mamano (jorix)]

Hi,

For other reasons (http://trac.osgeo.org/openlayers/ticket/3319) I was
looking at the third parameter ("drawing") on "modify" callback. 

And I thought ... "point" callback ("point" only occurs when drawing) could
receive a "drawing" parameter and for the first point would be false. So
this would be the first point.

What opinion about it?
