[feat] drawing optimisation

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
