backed-up window
A window whose contents are backed up, so that the window never becomes invalid, and therefore never needs to be redrawn except at application request.
See also: redraw, invalid, window

background colour
The colour with which to fill the parts of the view rectangle in which text (and paragraph fill colour, if one has been set) cannot appear. Examples of such areas are below the last line of the document and in the label and line cursor margins. May also be used to fill the left text margin, if one has been set.
