GTextEditor: Fix wrong width calculations with line-wrapping enabled

Browse source 
There were various little mistakes in the width calculations used by
the line-wrapping layout code.

With this patch, we should no longer see the horizontal scrollbar get
enabled with line-wrapping enabled. I will hide the scrollbar in a
separate patch.
