1823851 - WPT failures in css/css-transforms/skewY , for fuzzy pixels around edges of transformed SVG shapes

Status: RESOLVED FIXED

(Core :: SVG, task)

Description

[Daniel Holbert [:dholbert] (PTO until 2/24)]

We have some interop2023-relevant WPT failures here:
https://wpt.fyi/results/css/css-transforms/skewY?label=master&label=experimental&product=chrome&product=firefox&product=safari&aligned&view=subtest&q=label%3Ainterop-2021-transforms%20firefox%3Afail

These all are have some green SVG content that's transformed to precisely cover up a red shape. In every case, we essentially pass the test but fail due to the following antialiasing mismatch at one corner of the transformed content:

Found 2 pixels different, maximum difference per channel 1

We should just annotate these as a fuzzy allowance.

Also remove our internal .ini files that are unnecessarily generous in terms
of fuzzy threshold and pass/fail allowance.
