Struct RasterWindow 

pub struct RasterWindow<'a> {
    pub source_transform: [f64; 6],
    pub source_tile: [usize; 2],
    pub width: usize,
    pub height: usize,
    pub transform: [f64; 6],
    pub owner: &'a [u32],
    pub terrain: &'a [f32],
    pub owner_cells: &'a [[usize; 2]],
}

Geometry and terrain belong to the caller and can be reused across timesteps. Labels index owner_cells plus one; zero is outside the physical 2D footprint.
