// Description : This is a base class for GraphicsWindow (actually,
|
|
// GraphicsOutput) and DisplayRegion, both of which are
|
|
// conceptually rectangular regions into which drawing
|
|
// commands may be issued. Sometimes you want to deal
|
|
// with a single display region, and sometimes you want
|
|
// to deal with the whole window at once, particularly
|
|
// for issuing clear commands and capturing screenshots.
