14 Image scaling and padding and field order adjustment.
16 Normally resize is used to pad the producer's output to what the consumer has
17 requested after an upstream rescale filter first scales the image to maximise
18 usage of the image area. This filter also adjusts the field order to lower
19 field first if the frame property "top_field_first" has been set to 1.
20 Therefore, when done, it sets the top_field_first to 0. This filter is
21 automatically invoked by the loader as part of image sample aspect ratio
24 - Assumes lower field first output.
