Over 3000x3000 would most likely crash it, 1000x1000 is about as far as you want to go.

Altair managed quite a big picture for redalua, but it was in low quality. Agaska also did have quite a big picture, but used the tileing technique for GTA2lua.

The tileing technique is when you get close to another part of the map, then it'll appear and things you are far away from will be cleared from the memory, and then later reblitted when they are in range.

Smart idea I thought.
