```
Display of JavaView for viewing and interaction with 3d geometries. The display is subclass of an AWT canvas and fulfills the interface PvDisplayIf. It may be included inside any Java container with any layout manager.
A display may be obtained by three different ways:
1. Simple applets may directly create a display, add a geometry, and call the instance methods of the display to configure it.
2. A slightly advanced applet should obtain the default display from the central PvViewer instance using PvViewer#getDisplay(). This mechanism avoids any need to connect the geometry of the current project or viewer to the display.
3. In some cases an applet or project may need additional displays.
Simple applets may directly create a display and call its instance methods.
Each class fulfilling the interface PvDisplayIf can serve as a display in JavaView.
If the display is not added to an AWT container yet then external rendering does not work since this display has no Graphics yet.

  - addGeometry
```
public boolean addGeometry(PgGeometryIf aGeom)
```
    Add geometry to display. Display may show several geometries among one of them is the currently active geometry. The active geometry is the target for picking.
    After the first geometry is added, the display performs a fit() operation to center and scale the camera such that the geometry is completely visible in the display.
    The first geometry added to a display automatically becomes the active geometry. After having added several geometries the active geometry may be selected with selectGeometry().
    Note, default drawing order is PvGeometryIf#DRAW_ORDER_STANDARD which means, that z-depth of geometry elements are orderer in comparison with all other geometries. Except, if drawing order is PvGeometryIf#DRAW_ORDER_FRONT or PvGeometryIf.DRAW_ORDER_BACK then no comparison is done during display. Use method #setDrawingOrder(int, jv.project.PgGeometryIf) to modify the drawing order of a geometry after it has been added to the display.

    Set dimension of the external render image.
    This method modifies internally the size of the doubleBuffer, offscreen and antialias images, if active. When external rendering is switched off then the internal images are resized back to size of this display canvas.
    
    Parameters:
    
    width - width of external render image
    
    height - height of external render image

    Special flag for internal purpose is PAINT_ZOOM: Scale transformation matrix to simulate floating point accuracy in pixel integers. Required for PostScript printing to increase pixel accuracy.
    HACK: This PostScript Driver temporarily scales all integer valued quantities during display by a factor of PS_ZOOM to increase accuracy. The variable PS_ZOOM is set to allow to adjust all 'thickness' sizes as well. The thickness sizes are not scaled by PostScript, so we must do it in PvThickGraphics by hand. This procedure is very error prune.
    Setting flag PvDisplayIf#PAINT_ALL invokes a repaint() of the display, just for convenience.
