note that you can do the unpacking in the parameter list, if you
prefer:

>>> def render((r, g, b, a)=(1, 0, 0, 1)):
...     print r, g, b, a
...
>>> render()
1 0 0 1
>>> render((1, 1, 1, 0.5))
1 1 1 0.5

(but I'm not sure that combining unpacking and default values is
the best way to write readable code, though...)
