\brief The QBackingStore class provides the drawing area for top-level windows.
\brief The QBackingStore class provides a drawing area for QWindow.
QBackingStore enables the use of QPainter to paint on a QWindow with type
RasterSurface. The other way of rendering to a QWindow is through the use
of OpenGL with QOpenGLContext.
A QBackingStore contains a buffered representation of the window contents,
and thus supports partial updates by using QPainter to only update a sub
region of the window contents.
QBackingStore might be used by an application that wants to use QPainter
without OpenGL acceleration and without the extra overhead of using the
QWidget or QGraphicsView UI stacks. For an example of how to use
QBackingStore see the \l{gui/rasterwindow}{Raster Window} example.
