[PD] pix_movement weirdness

Hi,

I'm trying this:

[gemhead]
  |
[pix_video]
  |
[pix_yuv]
  |
[pix_movement 0.2]
  |
[pix_texture]
  |
[rectangle 5.3 4]


Pixels with an amount of movement below the threshold should become 
black, shouldn't they?

Instead of being zeroed they appear to be multiplied by a very small but 
non-zero factor, that is, I still see the original image but very very 
dark (while I do see white pixels where movement exceeds the threshold).

Now I'm seeing that [pix_threshold] suffers from exactly the same problem.

Am I missing something or is it just a bug?
Any workaround?

This is on Linux, with Pd Extended 0.42.5 (gem 0.92.3)
