function wSolnVec = OrthoEstMirrorDistRatio( polyBoundaryVecCell, normalAngle, RR_Rec, allViews )

%This function uses the silhouettes 2 and 3 to approximate the ratio of
%distances from the camera centres to the mirrors. 
%
%In principle, one could combine estimates from other pairs of silhouettes
%too -- but this would be a lot of coding for little benefit in increased
%accuracy, as Levenberg Marquardt easily turns the approximate solution
%into a very good solution.
