//@Module FIGUREPROPERTIES Figure Object Properties
//@@Section HANDLE
//@@Usage
//Below is a summary of the properties for the axis.
//\begin{itemize}
// \item @|alphamap| - @|vector| - Contains the alpha (transparency) map for the
// figure. If this is set to a scalar, then all values are mapped to the same
// transparency. It defaults to @|1|, which is all values being fully opaque.
// If you set this to a vector, the values of graphics objects will be mapped to
// different transparency values, based on the setting of their @|alphadatamapping|
// property.
// \item @|color| - @|colorspec| - The background color of the figure (defaults to a
// gray @|[0.6,0.6,0.6]|). During printing, this color is set to white, and then
// is restored.
// \item @|colormap| - @|color vector| - an @|N x 3| matrix of RGB values that
// specifies the colormap for the figure. Defaults to an @|HSV| map.
// \item @|children| - @|handle vector| - the handles for objects that are children
// of this figure. These should be axis objects.
// \item @|currentaxes| - @|handle| - the handle for the current axes. Also returned
// by @|gca|.
// \item @|doublebuffer| - Not used.
// \item @|parent| - Not used.
// \item @|position| - Not used.
// \item @|type| - @|string| - returns the string @|'figure'|.
// \item @|userdata| - @|array| - arbitrary array you can use to store data associated
// with the figure.
// \item @|nextplot| - @|{'add','replace','replacechildren'}| - If set to @|'add'| then
// additional axes are added to the list of children for the current figure. If set to
// @|'replace'|, then a new axis replaces all of the existing children.
// \item @|figsize| - @|two vector| - the size of the figure window in pixels (width x height).
// \item @|renderer| - @|{'painters','opengl'}| - When set to @|'painters'| drawing is based
// on the Qt drawing methods (which can handle flat shading of surfaces with transparency).
// If you set the renderer to @|'opengl'| then OpenGL is used for rendering. Support for
// OpenGL is currently in the alpha stage, and FreeMat does not enable it automatically.
// You can set the renderer mode to @|'opengl'| manually to experiment. Also, OpenGL
// figures cannot be printed yet.
//\end{itemize}
