    Class CjsTransform

    A Pixi Transform whose rotation and skew follow createjs.

    • The createjs values (degrees) are kept as written, so that reading them back gives exactly what was written (a degrees -> radians -> degrees round trip does not)
    • Pixi's own fields carry the same values in Pixi's terms (rotation in radians, skew.x = -skewX, skew.y = skewY, all in radians), so code that uses the Pixi node sees consistent values. A write made through Pixi (node.rotation, node.skew) is taken over as the new createjs value
    • The local matrix is built the createjs way: skew x (rotation x scale), i.e. the object is rotated first and then skewed. Pixi composes rotation and skew the other way round (skewed, then rotated as a whole); the two agree only while the rotation is 0 or skewX equals skewY. Published content is the reference, so createjs's composition is used
