Is it correct that the "displace" filter allows only displacements in

It works only with 8bit pixel formats, so yes.
Locally I have warp filter, which works by specifying 2D warp points
for distortion, thus not needing to use slow and cumbersome geq
filter.
Would be nice to add that to FFmpeg.
I've just added some examples (with geq filter) to my book.
