------- Additional Comments from Arvid Nilsson <anilsson at rim.com>
New version of patch incorporates a bug fix courtesy of Gordon Sun, prevent
LayerBSPTree from returning dangling pointers to the last frame's layers when
called with an empty polygon list in the next frame (by setting m_rootNode to 0
when build is called with empty polygon list).
