Detailed Description

In order to render a hex properly it needs to be rendered per row.

On 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 in the next hex. The foreground terrain needs to be drawn before to avoid decapitation 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 ...

• Surfaces are rendered per level in a map.
• Per level the items are rendered per location these locations are stored in the drawing order required for units.
• every location has a vector with surfaces, each with its own screen coordinate to render at.
• every vector element has a vector with surfaces to render.
