Subject: [PATCH] BGE BugFix [#25711]render.setBackgroundColor() does not work:
 Since rev.2 (hans ftw) we have a strange situation where horizon color was
 being used at Convert time for the WorldInfo background color (and for the
 fog). However through the Python API only the Rasterizer background color was
 being updated. On top of that the KX_KetsjiEngine.cpp::SetBackGround was
 using the WorldInfo bgcolor when render mode was the potato one (TEXTURED).
 Bottomline, when in potato mode the glClearColor used was the original one in
 worldinfo, not the API updated one in Rasterized.
