[osg-users] Constructor parameters of osg::Uniform

This is called implicit conversion and is totally legal.
In order to make to compiler avoid implicit conversion it can be tagged 
as explicit. As i've tumbled over this one more than once it might 
acutally be a good idea to change the uniform constructors which take 
only the name and "numElements".

@Robert:
Any insights?

Cheers
