SourceGutterRenderer.draw

Main renderering method. Implementations should implement this method to draw onto the cairo context. The background_area indicates the total area of the cell to be drawn. The cell_area indicates the area where content can be drawn (text, images, etc).

The background_area is the cell_area plus the padding on each side (two times the xpad horizontally and two times the ypad vertically, so that the cell_area is centered inside background_area).

The state argument indicates the current state of the renderer and should be taken into account to properly draw the different possible states (cursor, prelit, selected) if appropriate.
