Subtract Node

The Subtract Node ( shortcut: S key ) does an arithmetic subtraction where A is subtracted by B or ( A - B ).

Subtraction between multi-channel data types are done per-channel. If A and B have different channel amounts a cast is done to match the one with the most amount of channels.

Note: Subtraction is not commutative so value's order is important.
