Sets a new z-buffer, loading it from the zBufferFile file.
If zBufferFile is NULL (or anything other than a file handle) the current z-buffer will be removed. With no z-buffer loaded, all characters will be visible wherever they are placed on the screen.
If zBufferFile is a valid file handle, the z-buffer to be loaded must be the same width and height as the current scene, as set using the setSceneDimensions function.
No return value.
