[mzivic7]

Environment:

• Operating system: Linux(Arch), Windows
• Python version: 3.11.5
• SDL version: 2.26.5
• PyGame version: 2.3.2

Current behavior:

gfxdraw.aacircle draws weird lines when radius is larger than about 1000.

Expected behavior:

To draw nice and round anti-aliased circle.

Screenshots:

Test code:

import pygame
from pygame import gfxdraw
pygame.init()
screen = pygame.display.set_mode((1000, 800))
run = True
while run:
    for e in pygame.event.get():
        if e.type == pygame.QUIT: run = False
    screen.fill((0, 0, 0))
    gfxdraw.aacircle(screen, -500, 1000, 1200, (255,255,255))   # radius = 1200
    pygame.display.flip()
pygame.quit()

As mentioned in #2463 gfxdraw is supposed to be deprecated eventually. With the merge of #2800 looking like it'll come soon, I think we can then consider this as resolved as it's going to get. I'll add a checkbox to the original message so that this can be closed when gfxdraw is formally deprecated
