mtlcl410andClaude Opus 5.5 a08ec799f5 M2: tiling pattern cells sit at their XStep/YStep multiples at every scale (ISO 32000-2 8.7.3.1) (#4421 )

The cell pixmap was round(scale x step) pixels and repeated, but the cell
was drawn, and the paint transform mapped back, at the unrounded scale.
So the pixmap repeated a fraction of a pixel too far at every step (31 px
for a 30.56 px step at 110 dpi), and cells drifted further from their
place with every step from the pattern's origin.

Vendored hayro patch (25), `tiling_cell_pixels`: the cell is drawn at
round(scale x step) / step, so one step is exactly the pixmap's side, and
the paint transform uses that same scale. The side stays within 1 and the
existing 3000 px cap; a non-finite product keeps the scale and a bounded
side.

Tests: crates/render/tests/it/tiling_cell_placement.rs (fill, turned and
scaled matrix, stroke, all at 110 dpi far from the origin; the helper's
bounds).
