Subject: [PATCH] ox-latex.el: support sideways :float options for tables and
 figures

* lisp/ox-latex.el (org-latex--inline-image): support a 'sideways
option for the float, and add case to handle it with a \sideaysfigure
in the export.

(org-latex--org-table): support "sideways" instead of deprecated "sidewaystable"

* doc/org.texi (Tables in LaTeX export): Document use of :float sideways

               (Images in LaTeX export): Document use of :float sideways

This patch provides consistent :float sideways support for LaTeX export of both figures and tables.
