Detailed Description

Provides OpenGL context, window display, and event handling routines.

A user application may draw to the window's context by providing a user renderer. The viewer manages other display components such as the zoom views, text OSD, etc. It also takes care of window event handling and event passing, through which the renderer may interact with user inputs.
