I've made a patch (attached) that adds some methods with the type as
part of the method name for int, float and double.  I'm now able to
use shaders + variables in Python.

It _seems_ that the Python wrapping code can distinguish between
overloaded methods on the basis of number of parameters, but not on
type of parameter.  I vaguely remember something like this, but I
couldn't find explicit mention of it anywhere.

In anycase, if nobody objects, I'd like to apply this patch in a week
or two.  I'd also very much like to hear if I'm just being daft. :)

Thanks,
Charl
