Icon (Component)
Library: StdIcon
Necessary constants: I_USED
The Icon component contains a function that loads an icon archive using the Icon File Format (IFF) to an array. The icon's addresses are stored in a separate pointer array which makes possible direct access via DRAWICON (-> I_LOADFILE!).
Furthermore the function FT_DRAW is able to draw text in a user-defined font that is stored as IFF icon archive.
