Always use AwesomeResampling for lazy decoded images.

We don't know the real destination scale of lazy decoded images
and should not be making filter choices based on the
transformation matrix here.

Instead use AwesomeResampling for all lazy decoded images and
leaves it up to skia to decided if a more efficient filter can
be used at rasterization time.
