ffmpeg | branch: master | Stone Chen <chen.stonechen at gmail.com> | Thu Mar 14 12:47:45 2024 -0400| [de2fb43e785773738c660cdafb9309b1ef1bc80d] | committer: Marton Balint

doc/filters: Change rdiv (vf_convolution) documentation to reflect actual behavior

The documentation correctly states that the rdiv is a multiplier but incorrectly states the default behavior is to multiply by the sum of all matrix elements - it multiplies by 1/sum.

This changes the documentation to match the code.

Address trac #10889
