[pygame] Re: BUG: pygame.Rect collidepoint() flawed

["Guillaume Rava" <guillaume.rava@xxxxxxxxx>]

I want to elaborate on the bug I just posted because I just realized
that offset values in the top and left fields actually messes up a lot
of other things: right, bottom, bottomright, center, and all
calculated fields are bugged:
r = pygame.Rect(10,10,110,110)
> > > r.right
120

120
> > > r.center
(65, 65)
