Ting Fu 22d99589d8 lavfi/vf_drawbox.c: fix CID 1485004

Ting Fu f444be643e libavfilter: vf_drawbox filter support draw box with detection bounding boxes in side_data 
This feature can be used with dnn detection by setting vf_drawbox's
option box_source=side_data_detection_bboxes, for example:
./ffmpeg -i face.jpeg -vf dnn_detect=dnn_backend=openvino:model=face-detection-adas-0001.xml:\
input=data:output=detection_out:labels=face-detection-adas-0001.label,\
drawbox=box_source=side_data_detection_bboxes -y face_detect.jpeg

Gyan Doshi 1c76134fe3 avfilter/drawbox+drawgrid - add option to prevent overwriting of source pixels 
If the user-supplied color in drawbox and drawgrid filters is non-opaque,
the box & grid painting overwrites the input's pixels (including alpha).
Users typically expect the alpha of the specified color to only act as a key
for compositing on top of the main input.

Added option allows users to select between replacement and composition.
Tested and documented.

Gyan Doshi b3cb9bd43f avfilter/drawbox: rename variable for maximum thickness 
The present value name for maximum thickness is 'max' which results in a

Value renamed to 'fill'. Tested locally and documented.

Jean Delvare 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.

Clément Bœsch 1776177b7f lavfi: replace passthrough_filter_frame with a flag. 
With the introduction of AVFilterContext->is_disabled, we can simplify

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