Problem

Flowing liquids currently use param2 for the flow direction. As an example, this makes it impossible to use a colour palette with flowing water, without also messing up the way that the water flows and spreads. This is quite disadvantageous for a game such as MineClone 2.

Solutions

A different method should ideally be used to determine the flow direction of liquids, one that still allows for the use of a colour palette with the flowing liquid.
