-- t'GI.Gdk.Objects.DrawingContext.DrawingContext' is an object that represents the current drawing
-- state of a t'GI.Gdk.Objects.Window.Window'.
-- 
-- It\'s possible to use a t'GI.Gdk.Objects.DrawingContext.DrawingContext' to draw on a t'GI.Gdk.Objects.Window.Window'
-- via rendering API like Cairo or OpenGL.
-- 
-- A t'GI.Gdk.Objects.DrawingContext.DrawingContext' can only be created by calling 'GI.Gdk.Objects.Window.windowBeginDrawFrame'
-- and will be valid until a call to 'GI.Gdk.Objects.Window.windowEndDrawFrame'.
-- 
-- t'GI.Gdk.Objects.DrawingContext.DrawingContext' is available since GDK 3.22
