xcssmatrix

Cross-browser, spec compliant, XCSSMatrix shim.

XCSSMatrix

The XCSSMatrix class is intended to bring the functionality from WebKitCSSMatrix to other browsers, and NodeJS. The CSSMatrix interface was defined in the CSS 2D Transforms and CSS 3D Transforms Module specifications.

Its API is intended to match the spec. The tests have been copied from the WebKitCSSMatrix tests for 2D and 3D.

The implementation was largely copied from Firmin's FirminCSSMatrix object.

At the moment, it does not throw errors, which is (was) against the spec. See issue #1 for more.

Please create tickets(and/or tests) for any failing cases.
