Migrate old legacy code to the draw mamager/object mode. The old legacy version did not work with wireframe. By migrating the code to modern draw manager code we have mode control on the drawing process. Still background images do not work with OIT, the cause seems to be that the transparent pixels are treated as background pixels. Also There are some artifacts when working with Holdouts and DoF, this is because the draw engines do not pass the correct alpha values.
