  "message": "[Impeller] Correct advanced blending behavior. (#43283)\n\nInvestigated as part of\r\nhttps://github.com/flutter/flutter/issues/127232.\r\n\r\nThis took some time to work out, but:\r\n* The amount of blending applied to the source color needs to be\r\nweighted by the destination alpha, which is pretty sensible behavior.\r\nThis is in addition to applying source-over behavior with the resulting\r\nblended color.\r\n* All of the blend functions assume that the color is already\r\npremultiplied, so remove the unpremultiply/premultiply surrounding the\r\nblend call.\r\n\r\nAll of the blend modes now visually match up with the [Flutter\r\ndocs](https://api.flutter.dev/flutter/dart-ui/BlendMode.html), except\r\nfor ColorBurn and Saturation, which appear to have a slight\r\nmiscalculation going on with the red channel.",
