| // Debug builds because it triggers the ordering asserts in validate_edge_list() |
| // |
| // Attempted to solve this ordering issue by adding a variable epsilon in |
| // https://skia-review.googlesource.com/c/skia/+/1004396, but this had to be removed as it caused |
| // regressions in the fuzzer. |
