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 #GtkSourceGutterRenderer:xpad horizontally and two times the #GtkSourceGutterRenderer: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.
