Excellent (as Miller would say... or Mr Burns)
That's exactly what I was trying to do.
I thought I could simply send [symbol GL_BLEND( (and other constant
names) to the GL objects.
Also, I was missing the necessary [alpha] object.
By the way, in your
By the way, it seems to me that with this approach I can achieve:
- additive blending (by setting both sfactor and dfactor to GL_ONE)
- multiplicative blending (by setting for example sfactor=GL_ONE and
dfactor=GL_SRC_COLOR)
but NOT for example subtraction or difference... or am I missing
Errata corrige:

I meant sfactor=GL_ZERO
However the question remains:

other than that the solution is pretty much outlined in your question already.

Ok I just hoped there was a simple way to achieve add and multiply as well.
So can I assume ther isn't?

Well, since I use Windows pix_share_write and read don't work, but I
guess I could do the same without those objects.
Yes, this is one approach. I was looking for another approach that
wouldn't involve taking snapshots of the scene and adding

A) Use several [rectangle]s on a plane, get a snapshot of the

B) manipulate the camera input as pix, or as texture, and compose a
bigger pix, so only at the very end, for displaying, you would use a
rectangle
