Texture object method was requiring the width and height of the
framebuffer as arguments.  It was doing error testing on these
arguments but there is no reason to.  Copying a texture where part of
the texture goes outside the framebuffer is fine. That can happen
and is not a problem. The extra texels just get discarded. This also
saves having to know the width and height of the frame buffer
to make this call.
