+ Method to set cameras
# inverted camera zoom direction
+ camera and empty model in editor state
+ box marker
+ a list with all voxel types to give ids (Komponenten.ods)
# renamed wire shader to beam shader and reused old pure wireframe shader
# bugfix: Model::RayCast had wrong inverse
# new input option: editor deletion mode key
# can edit models: careful with negative coordinates (hangs up)
# rays are now normalized (ray-sphere intersection requires that)
# bugfix: input handling more robust if game state switches in between (all events go to the same state now)
# set the maximal model size in editor to 4096^3 to solve the negative coordinate problem
