Summary: Straight Onto fails in a file

Initial Comment:
I've discovered how Straight Onto doesn't do its work properly for non tiled 
renders. 

Download the attached file. 
Open it and set the time to 16 seconds. Now zoom in and out and see how the 
mouth of the character changes. 

The mouth ("boca") is composited by this:

Inline Paste canvas ("boca")
-Inline paste canvas ("lengua")
--Inline paste canvas ("lengua") -> Straight Onto
---Some layers to perform the tonge
--Region layer (wide open mouth) 
-Region layer ("boca")

At frame 16s the "lengua" (Straight Onto) layer is moved apart of the wide open 
mouth region layer. So the "lengua" and the wide open mouth layer wouldn't be 
shown. 
But notice that if you render the scene at that frame (exactly any frame after 
frame 15s) it renders the wide open mouth although it wouldn't be shown because 
the Straight Onto paste canvas layer is far away.

On the other hand it renders OK (mostly) if the tile render is used.


NOTE: the file looks for a image file called paper.png that is not included. It 
doesn't affect to the problem.

I've found a workaround. 
Place the Region layer (wide open mouth) over the Inline paste canvas
("lengua") that has the Straight onto problem. Make this inline paste
canavas composite blend instead of straight onto. Then invert the Region
layer and make it Alpha Over blend.
