Drawing context for GDK windows.
Gdk::DrawingContext is an object that represents the current drawing state of a Gdk::Window.
It's possible to use a Gdk::DrawingContext to draw on a Gdk::Window via rendering API like Cairo or OpenGL.
A Gdk::DrawingContext can only be created by calling Gdk::Window::begin_draw_frame() and will be valid until a call to Gdk::Window::end_draw_frame().
