Function blended_transform_factory

lib/matplotlib/transforms.py:2377–2388

Create a new "blended" transform using *x_transform* to transform the *x*-axis and *y_transform* to transform the *y*-axis. A faster version of the blended transform is returned for the case where both child transforms are affine.
