To me, the code does very few work (in both filters). Reusing these
few lines of code is bigger headache than having them duplicated.
BTW i agree with original comment in vf_drawbox.c: "A nice template
for a filter that needs to write in the input frame". Making trivial
example/template to be a reusable library seem over-engineering to me.
Drawgrid without setting a cell size makes a frame around the image,
so it does what drawbox should do. So if we fight for eliminating
spare code, i'd suggest dropping drawbox.
