'lb' is a deinterlacer, which doesn't need teh qscale info, so it works
after crop/expand like transdormations (but doens't work after scale!)
and putting it after crop is even faster as it doens't have to process the
image parts being cropped out.

for pp=0x77 (deblock, dering filters) it must be the first or at least
before any resizing transformation.
