[pygame] Cirle's clipping bug?

[Ludek Smid <ludek@sde.cz>]

Hi,

this piece of code crashes Pygame (release 1.2, WinNT). When you uncomment 
marked line, crash no longer occurs. I guess, there is problem with 
clipping. If you change width of circle to other value than 0 then 
everything will be ok.

And one more tip - try to set radius of circle to a lower value than width 
of the circle or event to a negative value. (Change xrange's first 
parameter to 0, -1, ..) :-)

import pygame, pygame.draw, pygame.time
from pygame.locals import *

pygame.init()
screen = pygame.display.set_mode((640, 480), SWSURFACE, 16)

center = screen.get_rect().center

# comment or uncomment following line
# screen.set_clip(0, 0, 639, 479)

for r in xrange(1, 480):
	print screen.get_clip(), center, r
	screen.lock()
	screen.fill((0x00, 0x00, 0x00))
	pygame.draw.circle(screen, (0xff, 0xff, 0xff), center, r, 0)
	screen.unlock()
	pygame.display.flip()
