<div>There is a function called vertexAt(QgsVertexId id)
which returns a QgsPoint, but the documentation is very
unclear on how to actually use this. What really is
QgsVertexId and how should it be constructed? Alternatively
there is vertices() or vertices_begin () which are iterators
that potentially could be used.</div>

<div>This all seems awkward and not documented well. What is the
best way to get a QgsPoint from a point feature which is
coming from a processing script like this?</div>
