William Deurwaarder 7c19684ee9 GPULightmapper exclude back-face triangles while calculating bounces ...

Edges that are at the edge of a plane, may get behind the scene and will hit
back-face triangles which where included in the lighting calculations. This
caused leaking of light at the edge of planes.

In case a ray hits back-face triangle, it is skipped in the bounce calculations.
