Detailed Description

Helper for rendering the map by ordering draw operations.

In order to render a hex properly, they need to be rendered per row. In this row several layers need to be drawn at the same time, mainly the unit and the background terrain. This is needed since both can spill into the next hex. The foreground terrain needs to be drawn before to avoid decapitating a unit.

In other words: for every layer for every row (starting from the top) for every hex in the row ...

this is modified to: for every layer group for every row (starting from the top) for every layer in the group for every hex in the row ...
