* only when we have to, not every time the graph is redrawn.
*
* Same goes for maintaining a pixmap to double buffer graph
* elements. Need to mark when the pixmap needs to updated.
*
*
* MAP_ITEM Indicates that the element/marker/axis
* configuration has changed such that
* its layout of the item (i.e. its
* position in the graph window) needs
* to be recalculated.
*
* MAP_ALL Indicates that the layout of the axes and
* all elements and markers and the graph need
* to be recalculated. Otherwise, the layout
* of only those markers and elements that
* have changed will be reset.
*
* GET_AXIS_GEOMETRY Indicates that the size of the axes needs
* to be recalculated.
*
* RESET_AXES Flag to call to RbcResetAxes routine.
* This routine recalculates the scale offset
* (used for mapping coordinates) of each axis.
* If an axis limit has changed, then it sets
* flags to re-layout and redraw the entire
* graph. This needs to happend before the axis
* can compute transformations between graph and
* screen coordinates.
*
* LAYOUT_NEEDED
*
* REDRAW_BACKING_STORE If set, redraw all elements into the pixmap
* used for buffering elements.
*
* REDRAW_PENDING Non-zero means a DoWhenIdle handler has
* already been queued to redraw this window.
*
* DRAW_LEGEND Non-zero means redraw the legend. If this is
* the only DRAW_* flag, the legend display
* routine is called instead of the graph
* display routine.
*
* DRAW_MARGINS Indicates that the margins bordering
* the plotting area need to be redrawn.
* The possible reasons are:
*
* 1) an axis configuration changed
* 2) an axis limit changed
* 3) titles have changed
* 4) window was resized.
