4316# An axis-aligned tile of at least four device pixels is rendered at device
4317# density and read bilinearly (nearest-neighbour images stay crisp). A rotated,
4318# skewed or tiny tile is rendered at `sub` times the density, or at least four
4319# pixels across, and read with a sub by sub grid of nearest lookups over each
4320# device pixel's footprint: rotated content keeps supersampled edges and a tile
4321# smaller than a pixel averages out.
