Sets matrix to be the affine transformation given by xx, yx, xy, yy, x0, y0. The transformation is given by: x_new = xx * x + xy * y + x0; and y_new = yx * x + yy * y + y0;
xxxx component of the affine transformation
yxyx component of the affine transformation
xyxy component of the affine transformation
yyyy component of the affine transformation
x0X translation component of the affine transformation
y0Y translation component of the affine transformation
Returns a new CairoMatrix object that can be used with surfaces, contexts, and patterns.
