It needs to be pointed out that you can mark the region sloppily by
including more than necessary.  Like using C-x C-p for marking the
current page (assuming that it's balanced with regard to previewable
constructs).

It's also worth pointing out that previewing the whole document tends to
be a lot less painful than one would think it to be.  preview-latex is
old software from a time when computers were running an order of
magnitude slower.
