I understand. You simply want to draw a cirle with a diameter that is an 
odd number.

I just tested this myself, and the following lines of code produce 
circles that are exactly the same, to the pixel:

pygame.draw.ellipse(somesurface, somecolor, (0,0,6,6))
pygame.draw.ellipse(somesurface, somecolor, (0,0,7,7))

My guess is that the diameter gets divided in half to find the radius 
using integer math, so 7/2 = 3

I tried passing a float as the diameter, but that did not help:

pygame.draw.ellipse(somesurface, somecolor, (0,0,7.0,7.0))
