Previous implementation set the whole fbo's width and height as the viewpoint. This may increase the numerical error as we may only has a partial region as the valid pixmap. So add a new marco pixmap_priv_get_dest_scale to get proper scale factor for the destination pixmap. For the source/mask pixmap, we still need to consider the whole fbo's size.
