//! This class constructs a 2D graphic buffer in a view. It <br>
//! manages a set of graphic objects and/or primitives. <br>
//! To draw the buffer, the following elements are required: <br>
//! - the override color <br>
//! - the font <br>
//! - a solid line type <br>
//! - thickness of 1 pixel. <br>
//! With this category , the user can drag the geometry <br>
//! stored in the buffer without changing the fixed <br>
//! background. This mechanism is reserved for the <br>
//! special driver Aspect_WindowDriver: if no other <br>
//! driver has been defined, nothing will be drawn. Both <br>
//! this driver and view mapping are used to draw the buffer. <br>
//! Warning <br>
//! - This class manages dragging only. It does not <br>
//! manage "sketching" or "rubberbanding". For example: <br>
//! - There is no empty constructor for this <br>
//! primitive. Therefore we must create a primitive <br>
//! in a dummy object simply to add this primitive to the buffer. <br>
//! - There is no Buffer->Add (anArrayOfPoints) <br>
//! method. Therefor it is not possible to add <br>
//! shapes to the buffer. <br>
//! - There are no Polyline->ChangeApoint () nor <br>
//! Circle->ChangeRadius () methods. Therefore <br>
//! we must call the primitive's destructor to modify <br>
//! the definition of one primitive in a buffer. <br>
//! - The Graphic2d_Image class is a primitive. For <br>
//! this class, we replace the definition of the image <br>
//! with a rectangle with the same size and the same position. <br>
//! - You can add or remove primitives to the buffer <br>
//! after creating and displaying it again. <br>
