Description

This function stores the screen image of the bounding rectangle defined
by the points ('Xleft','Ytop') and ('Xright','Ybottom') in an array which
is returned by the function.
The background is saved using the VMM (Virtual Memory Manager) of CA-Clipper.
You don't have to allocate memory...that's all done by the function itself.
Clipping is NOT performed.

This function can be used only if you have set the screen to a graphic mode
using FGLSetMode().


Syntax

  FGLGetBackground(< Xleft >,< Ytop >,< Xright >,
                   < Ybottom >) -> Array.
