I see that Balloon3D has been removed in the 3.9alpha images. Why?

I installed the 1.0.4 sar and it seems to run well in the latest squeak 
image released and I'm still reading the tutorial but I was wondering if 
there's a way to program directly in opengl inside squeak and which is 
the planned future for 3d support.

Thanks in advance.

Cheers,
