io.github.srs.model.illumination.raster.OcclusionRaster
Provide occlusion rasterization for Entity shapes.
Turns circles / rectangles into a discrete grid used for light blocking. Cells contain 0.0 (Cleared) or 1.0 (Occluded).
- Sampling at the center of each cell: (x + 0.5, y + 0.5).
- Coordinate scaling: world units * ScaleFactor => grid-space (pixels/cells).
- All min/max index ranges are inclusive and clamped to grid bounds.
