"transform animated" is confusing here. what transform? some transform inside
the picture pile, the scale transform used to raster it or something else? I can
tell by the picture layer code that this refer to the transform used to draw the
layer for which this picture pile represents the contents of but that's
impossible to know by just looking at this file.

I think this needs a comment at a minimum. Possibly a better name..
