[FFmpeg-user] curves filter and tmix filter, suggestions for improvement

I have two suggestions for improvement:
1. It would be nice if the curves filter could import curves files from
GIMP. GIMP can export curves files in two different formats, either the
default format or the "old curves file format". For the old format I
have a selfmade C# converter to the *.acf format which FFmpeg's curves
filter can import. But it would be better if FFmpeg could directly
import GIMP's newer curves format, because it contains more informations.
2. For the tmix filter it would be nice if it would accept "frames = 1",
meaning "no mixing at all, just a bypass mode". Then it's easier to
switch the filter on and off with a variable in batch file.
Please add to the documentation: "If the weights parameter is not
specified, the default is 1 for each frame".
