//! This class allows to map textures on shapes <br>
//!  Textures are image files. <br>
//!   The texture itself is parametrized in (0,1)x(0,1). <br>
//!  Each face of a shape located in <br>
//! UV space is provided with these parameters: <br>
//!    -      Umin - starting position in U <br>
//!    -      Umax - ending position in U <br>
//!    -      Vmin - starting position in V <br>
//!    -      Vmax - ending position in V <br>
//!  Each face is triangulated and a texel is assigned to each <br>
//!  node. Facets are then filled using a linear interpolation <br>
//!  of texture between each 'three texels' <br>
//!  User can act on : <br>
//!  - the number of occurences of the texture on the face <br>
//!  - the position of the origin of the texture <br>
//!  - the scale factor of the texture <br>
