[PD] pix_snap example?

[Peter Worth]

hi again.

following on from a similar topic i posted yesterday, can anyone give
me an example patch with pix_snap in? the help patch for it seems to
be not very helpful to beginners..

is the rendering order important when doing this? where can i read
more about this type of thing in general? (why wont pix_convolve work
on textures is another thing i want to understand)

thanks for any info.
