[PD] "dummy" pix_crop question

[Matteo Sisti Sette]

Hi,

Not in the sense of a question asked by a dummy, but a question about a 
dummy [pix_crop] :)

Well the question is this: given this setup:

[gemhead]
  |
[pix_film]
  |
[pix_crop]
  ...

When the pix_crop is set to 0,0 offset and a size equal to the input 
image size, that is it is identical to no crop at all, will it consume 
the same amount of CPU as a nontrivial crop?

And by the way, I suppose that (at least when the crop is actually 
nontrivial) when the input image changes, performing the crop means 
actually copying all the pixels within the cropped region, doesn't it?

thanks
m.
