Where is this POINT_SMOOTH property coming from?  I don't see it in https://cvs.khronos.org/svn/repos/registry/trunk/public/webgl/doc/spec/WebGL-spec.html anywhere....

I'm not sure why it isn't there. I'm guessing since using the literal works, it should be in the spec.

I talked to Vlad on IRC about this. He said POINT_SMOOTH isn't available in ES 2.0, which is why it is missing from Minefield.

I'm worried it may not make it into the draft spec and will be removed from Webkit and Chrome. So I'll ask some devs who are working on the Khronos spec what they think.

POINT_SMOOTH is indeed not in the current (near final) WebGL spec, and we are now properly rejecting invalid pnames in enable().
