jit.gl.layer 'drawto' confusion

Hi.

I'm having issues getting my head around how drawto and jit.gl.layer work. I have a jit.movie outputting a texture to to jit.gl.layer, which is addressed to a named jit.world object. In the jit.gl.layer tutorial patch this seems to work perfectly, but in my patch jit.gl.layer is being ignored (i.e. movie is drawing directly to the jit.world).

I've had long term issues with this, and I've generally found with this setup is that *sometimes* (if you, for examples, instantiate the objects in a certain sequence and generally click around a bit) this works, and sometimes it doesn't. I'm sure it's my fault due to not understanding the paradigm fully, but I really am stumped, especially as the tutorial patcher seems fine.

How do I ensure that jit.gl.layer works as intended?

I have attached an example patch, which you can contrast to the jit.gl.layer tutorial patch.

Thanks for any help or insights!
