[Patch] Stencil shadows artifacts

[Eugene]

Our QA team found problem with stencil shadows. When light source is placed inside the object then shadows sometimes looks good, sometimes bad and sometimes partially good and partially bad as on screenshots

The reason is that when shadow is extruded in opposite directions the shape of dark cap of the shadow volume is very important and McGuire method that simplifies it is unapplicable.
