- GD:
. Added the "scatter" image filter (IMG_FILTER_SCATTER) to apply a scatter
filter to images. This filter has the following prototype:
imagefilter($im, IMG_FILTER_SCATTER, int $sub, int $plus, array $colors = []);
The $colors array can be populated with a set of indexed colors where to

Note, the result of this filter is always random.
- Hash:

used by storage systems, such as iSCSI, SCTP, Btrfs and ext4.
