Summary0029667: Visualization, TKV3d - User-defined texture coordinates corrupted by StdPrs_ShadedShape
DescriptionIt is impossible to map a texture to a BRep face when it has no underlying geometrical surface even if it contains user-defined Poly_Triangulation with valid pre-normalized UV nodes.

fillTriangles() function in StdPrs_ShadedShape.cxx tries to transform the UV points obtained from Poly_Triangulation using the UV parametric range of a face and this breaks the texture mapping in case of a void UV range. It looks logical to pass non-transformed user-defined UV coordinates directly to the renderer as texture coordinates in such a case.
