Currently the method ray_hits_triangle determines triangles not to be hit by
a ray due to an epsilon that is too big. In practice those triangles are hit by
those rays.
This is fixed by introducing a smaller epsilon.
This fixes the leaks in the model of @jcostello (see below) given in #51638. Also notice that the shadow cast by the roof of the veranda was incorrect.
