\class CBackground
\ingroup GameLogic
\brief The CBackground class draws the multi-layered background of each arena.
The backgrounds are identified by their number. Single-layer backgrounds do
not have description files. Multi-layer backgrounds have a description file
which has the following format:
\li First line: number of layers(int)
\li For each layer: First line: filename (relative to gfx directory)
\li For each layer: Second line: x-displacement(int) y-displacement(int) distance(double)
Extra layers can be added to the background. These are for dead fighters in
team game mode.
