preview-latex is not useful for previewing page layout.  It's only
useful for a subset of elements, like most math.  Use C-c C-v to start a
page-based previewer after compiling your document.

For those elements for which preview-latex _is_ useful, it beats the
pants off using a separate page-based previewer.  So it makes sense to
have it available even if it does not cover all use cases of a true
page-based previewer.
