GradientTransform class

Base class for transforming gradient shaders without applying the same transform to the entire canvas.

For example, a SweepGradient normally starts its gradation at 3 o'clock and draws clockwise. To have the sweep appear to start at 6 o'clock, supply a GradientRotation of pi/4 radians (i.e. 45 degrees).
