Tests per a __init__
====================

>>> im = pygame.Surface((20,40))
>>> rc = pygame.draw.circle(im, (255,0,0), (10,20), 4)
>>> f = fons.Fons(im)
>>> f.rect
<rect(0, -40, 20, 80)>
>>> f.image.get_size()
(20, 80)
>>> all(f.image.get_at((x,y))==f.image.get_at((x,y+40)) for x in range(20) for y in range(40))
True
>>> im = pygame.Surface((30,25))
>>> rc = pygame.draw.circle(im, (0,0,255), (10,10), 3)
>>> f = fons.Fons(im)
>>> f.rect
<rect(0, -25, 30, 50)>
>>> f.image.get_size()
(30, 50)
>>> all(f.image.get_at((x,y))==f.image.get_at((x,y+25)) for x in range(30) for y in range(25))
True


Tests per a update
==================
>>> f.update()
>>> f.rect
<rect(0, -24, 30, 50)>
>>> f.update()
>>> f.rect
<rect(0, -23, 30, 50)>
>>> for n in range(654):
...    f.update()
>>> f.rect
<rect(0, -19, 30, 50)>
