The basegfx Triangulator is used in slideshow with canvas to triangulate the mask geometres. This uses tools::isPointInTriangle which uses basegfx::tools::arePointsOnSameSideOfLine. This uses the cross product to solve and for tests against zero the fTools::equalZero call. The triangulator then uses the more precise rtl::math::approxEqual to test if one of the points of the triangle is equal to the test point. In rare cases this can lead to a position where a point is seen as inside the triangle wrongly because it is not detected as equal to one of the triangle points. To solve, use increased accuracy.
