//This Assertion ensures that the transform of the given view matrix, i.e., dx, dy must be both integers in Skia.
//We disable it because in our PictureLayer.PreRoll and Paint function, we use alignToPixel() to align the view matrix
//before creating RasterCache which cannot meet this constraint due to the involved devicePixelRatio.
//Enable it when we find a way to fix this alignment issue
// D.assert(() => {
// var x = this.matrix[2] * devicePixelRatio;
// var y = this.matrix[5] * devicePixelRatio;
// this.matrix[2] = (x - (int) x) / devicePixelRatio; // x
// this.matrix[5] = (y - (int) y) / devicePixelRatio; // y
//
// D.assert(Mathf.Abs(this.matrix[2]) <= 1e-5);
// D.assert(Mathf.Abs(this.matrix[5]) <= 1e-5);
// return true;
// });
this.matrix[2] = 0.0f;
