[jitter] Bug (?) with jit.gl.slab and @automatic 0

Hello.

Yes its me again! Can someone please take a look at this patch, and  
verify that its behavior makes sense?

I have all my gl objects at automatic 0.

I have a jit.qt.movie @unique 1, with a LOW framerate, which is  
setting the contents of two textures which feed a and b side of a mixer.
This mixer has a gate on it, which demonstrates the bug.

if the gate is closed, the mixer is only banged to render when the  
textures are updated, IE, at a slow rate.

If the gate is open, the mixer renders at the main clock speed. The  
output of the mixer is this mode is NOT the same as when the gate is  
closed, even though the contents of the textures and their assignment  
REMAINS THE SAME (this is the bug)

The patch below demonstrates. I do not think this behavior is correct.  
If the contents of the textures are not changing during the bangs that  
the slab mixer is being updated.

I believe the proper behavior is that gate OPEN is the SAME as gate  
CLOSED.

Anyone care to explain whats going on here behind my back? I need the  
above functionality for a project - specificially for frame blending  
two frames of a movie to make low framerates looks nicer. Regardless  
of the specific goal, I think this behavior makes little sense....

#P comment 96 311 100 196617 someone explain to me why turning this  
gate on seems to replace the values of my mixers second input (the  
texture)? Regardless of how fast I bang my mixer I should get the same  
results of the contents of the textures it is currently using. No? My  
textures are only updated when the jit.qt.movie updates. Thus its  
value and contents SHOULD NOT CHANGE during bangs to the mixing slab?  
Am I crazy?;
