That sounds like it might be it, I'll need to try that later on.
I think it's the trick with the resize and propagating that to the child
that I was missing...
What I want is that the child can resize horizontally as the window is
resized, but this will result in the child vertical dimension changing,
so I need to propagate that changed vertical size back up to the
scroll...
