Box-drawing characters, also known as line-drawing characters, are a form of semigraphics widely used in text user interfaces to draw various geometric frames and boxes. These characters are characterized by being designed to be connected horizontally and/or vertically with adjacent characters, which requires proper alignment.
Immediate mode is an API design pattern in computer graphics libraries, in which . the client calls directly cause rendering of graphics objects to the display, or in which; the data to describe rendering primitives is inserted frame by frame directly from the client into a command list (in the case of immediate mode primitive rendering),
A graphical user interface, or GUI [a], is a form of user interface that allows users to interact with electronic devices through graphical icons and visual indicators such as secondary notation. In many applications, GUIs are used instead of text-based UIs , which are based on typed command labels or text navigation.
Sketchpad ran on the MIT Lincoln Laboratory TX-2 (1958) computer at the Massachusetts Institute of Technology (MIT), which had 64k of 36-bit words.The user drew on the computer monitor screen with the recently invented light pen, which relayed information on its position by computing at what time the light from the scanning cathode-ray tube screen is detected.
Scripts are stored as either plain text files, usually with a .mrc file extension, or as INI files.They, however, can be stored with any extension. Multiple script files can be loaded at one time, although in some cases, one script will conflict with another and cause one or both of them to no longer work properly.
Inkscape is a vector graphics editor.It is used for both artistic and technical illustrations such as cartoons, clip art, logos, typography, diagrams, and flowcharts.It uses vector graphics to allow for sharp printouts and renderings at unlimited resolution and is not bound to a fixed number of pixels like raster graphics.
SCRIPT/VS was a SCRIPT variant developed at IBM in the 1980s. DWScript is a version of SCRIPT for MS-DOS, named after its author, D. D. Williams, [14] but was never released to the public and only used internally by IBM. Script is still available from IBM as part of the Document Composition Facility for the z/OS operating system.

X provides the basic framework, or primitives, for building such GUI environments: drawing and moving windows on the display and interacting with a mouse, keyboard or touchscreen. X does not mandate the user interface; individual client programs handle this. Programs may use X's graphical abilities with no user interface.
