cef42ded8d drawbox: Respect thickness parameter
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.

1776177b7f lavfi: replace passthrough_filter_frame with a flag.
With the introduction of AVFilterContext->is_disabled, we can simplify
the custom passthrough mode in filters.

This commit is technically a small compat break, but the timeline was
introduced very recently.
