add some generator to test the optoimisation:
adjust_brightness.py:
set some rectangle to rerify the consant of brightnes
keyborad_input.py:
is an exenmple of non blocking input reading
angleInteractive.py:
is an interactiv version to test the angle.
you can separatly set the lenght of each segment
you can set the angle
it must be run without brightnes optimization because mey be lenght have an importance
the feature implement a paper: https://art-science.org/journal/v7n4/v7n4pp155/artsci-v7n4pp155.pdf
there is some generator to test the optimisation in: ./clitools/generators/drawingTests/
Now, all the optimisation will be in ./libs3/plotOptimizer.py
in ./libs3/tracer3.py the adding of point is avoid an will be replace by the optimisation from the paper
