Detailed Description

Window handle and context structure.

A window is a small rectangular area on the screen backed by its own bitmap where you can draw.

A window can contain any number of children sub-windows that can be depth arranged with respect to their siblings.

At any time, a window and all its children can be drawn into another bitmap to display a complete screen, taking depth and overlapping into account.

This rendering model is commonly referred to as screen composition, and is quite popular among modern windowing systems.
