Cant use stroke_weight for points

[arieltl]

A clear and concise description of what the bug is.
in processing.py you can use strokeWeight to change the size of points but in p5py points seems to always be 1 pixel regardless of using stroke_weight or not.

Thanks @portalgamesmais. Could you provide a simple example test sketch?

[arieltl]

in processing.py the following sketch:

def setup():
    size(200,200)
    noLoop()

def draw():
    background(0)
    stroke(255)
    point(10,50)
    strokeWeight(10)
    point(50,50)

results in:

wile in p5py the following sketch:

from p5 import *


def setup():
    size(200,200)
    no_loop()

def draw():
    background(0)
    stroke(255)
    point(10,50)
    stroke_weight(10)
    point(50,50)

if __name__ == '__main__':
    run()

results in:

I also have this problem. I have installed p5 using pip. Since this was my first try with p5 it took me a while to convince myself that this is a bug.

For anyone thinking about working on this issue: The way that points are rendered in Processing(Java) is surprisingly complex under the hood due to support for strokeCap and how the behavior aligns with PostScript / CSS. So, in addition to strokeWeight() making points bigger, strokeCap() may make points invisible.
