The drawbox video filter is drawing lines one pixel thinner than
requested. The default thickness is 4 pixel but in fact the lines
drawn by default are only 3 pixel wide.
Change the comparisons in the code to fix this off-by-one bug. Also
change the default thickness from 4 to 3 to minimize the unexpected
changes from the user's perspective.
As I was already touching these lines, I also removed the "maximum" in
the thickness parameter description, as I don't think it was adding
any value and I even found it confusing.

The checks are replaced by av_assert0() as the conditions should
be impossible. If these asserts fail, there is a bug elsewhere

Conflicts:

The added condition is impossible to occur and thus is added to the assert.
The assert is not removed from the default case, as the default case cannot
occur. Thus either it should stay as is or the case as a whole be removed.
For extra safety, to ensure this doesnt change the assert is changed to
av_assert0()
