Fix point light shadows for SRP

                         var settings = new DrawShadowsSettings(cullResults, lightIndex);

+                        // The view matrix for point lights flips primitives. We fix it here (by making it left-handed).
+                        view.SetRow(1, -view.GetRow(1));
