//! This class defines Windows NT display device. <br>
//! A Graphic Device defines color management. Windows can run in three <br>
//! different color modes depending of the installed graphic board: <br>
//! - Low color resolution which allows us to use 16 predefined pure <br>
//! colors for drawing lines and unlimited number of dithered colors <br>
//! for window's background, solid filled areas etc. Here Graphic Device <br>
//! will approximate requested colors by existing ones for line colors <br>
//! ( really this approximation is doing by Windows ). A dithering <br>
//! technique will be used for window's backgrounds, solid fills etc. <br>
//! ( this is doing by WIndows also ). A dithering techique will be use <br>
//! for solid fill. <br>
//! - Medium color resolution which requires a Windows palette manager. <br>
//! This mode takes after X window system's PseudoColor Visual. The <br>
//! application can create a LOGICAL PALETTE to represent 20 reserved <br>
//! by Windows colors and 236 programmable ones. It's possible to reserve <br>
//! odd entries in the palette for highlighting purposes ( but real <br>
//! technique is not the same as in X window system - see Windows manual ). <br>
//! It's possible to create several logical palettes. To do it create <br>
//! other GraphicDevice but in this case color "flicking" is possible. <br>
//! - High color resolution. Here 65 536 or 16 777 216 colors are available. <br>
//! Any color we like will be exactly displayed on the screen, but <br>
//! highlighting technique is not available. This mode often called <br>
//! TrueColor but it's not the same as X window TrueColor. <br>
//! A Graphic Device also defines physical dimensions of the screen. <br>
