Default background color is black instead of (204, 204, 204) #134

When no background() call is made, the default canvas background in mewnala is black.

Expected behavior

The default background should be (204, 204, 204), matching Processing’s behavior.

Actual behavior

The canvas defaults to black.

Reproduction (mewnala)

from mewnala import *

def setup():
    size(200, 200)

def draw():
    circle(100,100,50)

run()

Equivalent Processing sketch (expected behavior)

void setup() {
  size(200, 200);
}

void draw() {
}
