In this case (p0 - 2 * p1 + p2) is equal to zero. 2075141 1 webkit-bug-importer 2024-11-14 13:12:16 -0800 <rdar://problem/139904014> 2075145 2 sabouhallawa 2024-11-14 13:22:35 -0800 Pull request: https://github.com/WebKit/WebKit/pull/36653 2075226 3 ews-feeder 2024-11-14 15:54:43 -0800 Committed 286618@main (dae159bae231): <https://commits.webkit.org/286618@main> Reviewed commits have been landed.
