*** Image smoothing can now be explicitly enabled or disabled.
Smoothing applies a bilinear filter while scaling or rotating an image
to prevent aliasing and other unwanted effects. The new image
property ':transform-smoothing' can be set to t to enable smoothing
property ':transform-smoothing' can be set to t to force smoothing
and nil to disable smoothing.
