Detailed Description

Window support for C-Menu - EXPERIMENTAL.

This file contains functions for managing NCurses windows and color settings for the Chyron structure for function key labels and mouse click handling. This file is a work in progress and may be subject to change as the C-Menu project evolves. Generally, don't try to use it yet unless you want complete the half-done code modifications.
