Dylan M. Taylor 58cd22d4ff security(doc): compute auto-slice coverage per band, not per cell ...

auto_slices tested every grid cell against the full slice-rectangle list
(covered(x, y) = taken.iter().any(...)). With slice edges forming the
grid, that is cubic in the slice count, so a crafted document's slice
arrangement could stall ordinary canvas drawing on the UI thread.

For each row band, mark covered x-cells in a single pass over the rects
that span the band, then scan the precomputed cells. This drops the inner
work from O(rects) per cell to O(1), while producing the same tiling.
