Pylint fixes for py_draw.py

[MyreMylar]

As far as I can tell this module is used exclusively for testing the real draw functions in draw.c. As such I was a little more ruthless in linting and tried to maintain only the function interfaces that were equivalent to the draw.c functions.

The other problem with it is that there are lots of TODOs all over it that I didn't really want to get into. I feel like linting errors and fixing TODOs are two entirely different things that shouldn't really be jumbled together, as such I ran pylint with fixme disabled for this file.

Disabled alerts:

• Only one this time:

def _multi_lines(surf, color, closed,  # pylint: disable=too-many-arguments
                 points, width=1, blend=False,
                 aaline=False):

This function is used to implement the interfaces of both draw_line() and draw_aaline() two functions that are already right at pylint's limit for function arguments, thus it wasn't really possible to cut the fat without splitting it into two functions - which would remove the point of having it all in one shared function in the first place.

Remaining warnings after this PR (with fixme disabled)

Tested using:

pylint src_py/draw_py.py --extension-pkg-whitelist=pygame --disable=fixme

Yeah, this module was supposed to be a python implementation of the drawing algorithms.

• comparison testing with different implementations
• debugging, and implementing new algos is easier with python
• useful for teaching.
• perhaps very fast when JIT compiled on things like pypy
