Add handle on environment texture in OpenGl_Workspace. Add a new parameter UseEnvironmentTexture to the Graphic3d_ZLayerSettings. OSD layers don't use environment texture by default. zbuffertrihedron doesn't use environment texture. vzlayer can enable/disable environment texture mappping. Delete unnecessary files Graphic3d_TypeOfSurfaceDetail.hxx and V3d_TypeOfSurface.hxx. Delete functions SurfaceDetailType and SetSurfaceDetailType functions from Graphic3d_CView. Delete functions SurfaceDetailState and UpdateSurfaceDetailStateTo from OpenGl_ShaderManager. Delete class OpenGl_SurfaceDetailState. Delete functions SurfaceDetailType and SetSurfaceDetailType from OpenGl_View. Delete functions SetSurfaceDetail and SurfaceDetail() from V3d_View. Delete functions SetDefaultSurfaceDetail and DefaultSurfaceDetail from V3d_Viewer. Delete draw command VSetTextureMode. Add description in dox.
