Andrew:

Yes, it works! (small cosmetical issue - it has no Info text associated with it...)

I have updated "info" for Crop & Position and GG will check it in later. Also, updated info for some of the ffmpeg filters that were newer to include: Mandelbrot and N_Body (only show if using Cuda), F_chromahold, F_colorhold, F_dedot, F_lagfun, F_maskfun, F_rgbashift, F_scale_cuda, F_tpad, F_yadif_cuda, AND AUDIO F_anlmdn, F_asoftclip, F_deeser, and F_volumedetect. I hope I found them all.

Andrea: did you try F_maskfun and get that working? The Icon for Crop & Position will be worked to make it fit into the themes better - hopefully today.

One question: Does it work like a real Crop, i.e. cutting off the
extra parts and getting a smaller size? Or does it just make the cut
parts transparent and keep the original size?

I don't know the answer to the above technically -- maybe someone else has tried it and can answer this. Phyllis
