* fix(redact): remove a stroked path by the box its stroke paints Path redaction tested a path's construction box against the marks. A horizontal or vertical stroke has a zero-area box, which overlaps nothing, so its drawing commands stayed beneath the overlay; a wide stroke whose points lie beside a mark but whose ink reaches into it stayed too. The interpreter now tracks the line width, miter limit and join style (`w`, `M`, `j`, and `LW`, `ML`, `LJ` through `gs`) and, for a stroking operator, grows the box by half the width (at least one unit), times the miter limit when the path has mitred joins, scaled by the CTM's largest stretch, before the hit test. The bound is conservative: a stroke near a mark may now go where before it stayed. * address review: pad hairlines by half a unit, rectangles for their corners, square caps by sqrt 2 * review: test a kept clip against the path as constructed * address review: a line state set between a path and its stroke no longer lets the stroke skip the redaction test * address review: line-state operators read the operand before the operator
