Bayer dotted map and 3D globe look

Bayer is the classic-Mac dither preset: a 4×4 ordered threshold matrix that turns continuous brightness into binary on/off pixels in a geometric grid. It looks like early Mac, early console and 1980s software graphics. Unlike Halftone's round dots, the Bayer grid is square and axis aligned. cellSize controls the matrix tile pitch (4 to 16 pixels), and intensity goes from passthrough toward pure binary.
