[away3d] load progress in AS3

[wesm]

Hi,

I would like to build a progress bar for loading my awaybuilder scene.
I didn't see a progress event for loading Collada model.

I am using Event.COMPLETE to call a loadComplete function, but there
doesn't seem to be a Event.PROGRESS.

loader.addEventListener (Event.COMPLETE, this.loadComplete);

I am new to away3d and AS3, so I apologize for the simple question.

Thanks,

Wes
