This is what I was roughly thinking of.  One can't move the function
from Texture to Image as not all textures have images.  You could have
it in both places, or just have a function in the osg namespace and
provide all the input variables for it.

As a general guide, a Object::getMethod() typically gets a property
from an object, but if a method computes the value on the fly from
input variables I nornally opt for Object::computeMethod().   assume
is a bit wishy washy so probably isn't ideal - this was used in the
original glTexStorage PR but I probably should have suggested a
change.

We have to think about both master and the 3.6 branch here.  The later
the aim is to maintain binary compatibility so our options are more
constrained.

Cheers,
Robert.
