DESCRIPTION
       This function is	used to	provide	a rendertarget with a camera, enabling
       the 3D processing part of the pipeline. The object that is used as dst
       will  be	 converted into	a camera- type,	and it is from the perspective
       of this object that the 3D scene	will  be  processed.  The  destination
       rendertarget  is	 either	 the primary attachment	of the object used for
       dst , or, if the	long-form argument is used,  a	specific  rendertarget
       via tgt . The camera parameters are tuned using near , far , and	aspect
	which are used to compute the projection matrix	 that  will  be	 acti-
       vated.  The  boolean toggles front  and back  determines	which sides of
       the model primitives that will be drawn.	Setting	the linew  argument to
       something larger	than 0 will enable wireframe drawing mode for the cam-
       era and disable normal processing. the argument form providing  projec-
       tion    will  replace  the current projection matrix of the camera with
       that of the table.
