[PD] unwanted blur with gemframebuffer and pix_buffer

Hey all,

I use the attached patch to [pix_buffer] snapshots of a scene with an image
rendered on a sphere.
Then I read from the buffer the scene, and texture it on another rectangle
(to apply other effects).

It works fine, but I noticed that the [pix_buffered] scene looses details,
becomes somewhat blurred.
I'm not sure what's wrong...

I'm on Ubuntu Lucid 10.4, pd-extended 0.42.5, NVIDIA® Quadro FX 880M.

If you have the time to check the patch, any help is appreciated.
Just load an image and toggle to switch between normal rendering and
[pix_buffer]ed scene.

cheers,
