+\subsection{Sizehint winprops}
+
+Additionally, the winprops
+\code{max_size}\index{max-size@\var{max_size}},
+\code{min_size}\index{min-size@\var{min_size}},
+\code{aspect}\index{aspect@\var{aspect}},
+\code{resizeinc}\index{aspect@\var{resizeinc}},
+and
+\code{ignore_max_size}\index{ignore-max-size@\var{ignore_max_size}},
+\code{ignore_min_size}\index{ignore-min-size@\var{ignore_min_size}},
+\code{ignore_aspect}\index{ignore-aspect@\var{ignore_aspect}},
+\code{ignore_resizeinc}\index{ignore-aspect@\var{ignore_resizeinc}},
+may be used to override application-supplied size hints. The four
+first ones are tables with the fields \var{w} and \var{h}, indicating
+the width and height size hints in pixels, and the latter ignore
+winprop is a boolean.
+
+Finally, the boolean
+\code{userpos}\index{userpos@\var{userpos}} option may be used to
+override the \code{USPosition} flag of the size hints. Normally,
+when this flag is set, Ion tries to respect the supplied window
+position more than when it is not set. Obviously, this makes sense
+only for floating windows.
