[jitter] Re: [Bug report] Jitter texture disparition

Hi,
could you give help about rendering order questions.

1) it seems Tut 31 - more render destination - is not update, 
look at page 278 :

"Each time a jit.gl.render object receives a bang message, it draws all of the GL group objects that have been added to its context. 
It draws the objects in the order in which they were added to the context. 
In this case, the yellow circle was added to the draw context named "B" after the blue circle, so it appears on top."

It's False : if you select the yellow circle last, the blue one appears on top and the yellow circle is hidden.

Am I right ?
I'm on OSX with jitter 1.6.3 and Max 4.6.

2) since rendering order theorie is not so obvious some clarification are required :
- how to render in proper order (I mean with gl's) ? 
- how (and why) to use the @automatic 0 ? (nothing about this attribute in jitter tutorial) 
- Does a patch with several gl objects need several renders ?
- and finally what are the rules with rendering ? (since I'm personally not an open gl specialist or video engineer) 

...

So many thanks .
