[FFmpeg-devel] [PATCH] Add 'drawgrid' video filter

[Andrey Utkin]

I was not aware of drawutils, i just derived from drawbox with
changing condition of drawing the pixels. So i think if drawbox is ok,
this implementation of drawgrid is also ok.
Anyway thanks for pointing to drawutils, i found the way drawbox
modifies the image too much low-level.
Maybe later i'll update the filter to use it.
