0023188: Regression in SCATexturedShape in SSP sample

Browse Source 
OpenGl_View::RedrawLayer2d()
- lighting and 1D/2D texturing disabled so as
not to interfere with layer drawing, layer items should enable
textures if necessary and disable them at the end;
- French comments removed;
- redundant lighting state changes removed

OpenGl_GraphicDriver::BeginLayer()
- useless code enabling 2D textures removed
