-ms-interpolation-mode property warned as invalid

[awayken]

The -ms-interpolation-mode property is warned as being invalid. Interpolation mode is mostly used in my code to help improve IE 6 and 7 rendering of images that are scaled down. CSS-Tricks mentions it in their article IE Fix: Bicubic Scaling for Images.

bicubic.styl

img {
    -ms-interpolation-mode: bicubic;
}

bicubic.json

{
    "alphabetical": true,
    "borderNone": true,
    "brackets": false,
    "colons": false,
    "colors": false,
    "commaSpace": true,
    "commentSpace": false,
    "cssLiteral": false,
    "depthLimit": false,
    "duplicates": true,
    "efficient": true,
    "enforceBlockStyle": false,
    "enforceVarStyle": false,
    "extendPref": false,
    "globalDupe": false,
    "indentSpaces": 4,
    "leadingZero": true,
    "maxWarnings": 10,
    "maxWarningsKill": false,
    "mixed": false,
    "namingConvention": false,
    "parenSpace": false,
    "placeholders": true,
    "semicolons": false,
    "universal": true,
    "valid": true,
    "whitespace": true,
    "zeroUnits": true,
    "zIndexDuplicates": false,
    "zIndexNormalize": false
}

Output:

Warning:  property is not valid
File: bicubic.styl
Line: 2: -ms-interpolation-mode: bicubic;
