lawnjelly 70cd25f3eb Tighter shadow culling - fix light colinear to frustum edge 
In rare situations if a light is placed near colinear to a frustum edge, the extra culling plane derived can have an inaccurate normal due to floating point error.
This PR detects colinear triangles, and prevents adding a culling plane in this situation.
