To draw shapes with shaders (OpenGL 2 and later), one need to upload
vertices and associated normal vectors and texture coordinates to
vertex attributes of your shaders. Use these functions to set the
indices (addresses) of the vertex attributes in your currently active
shaders before calling the above geometry functions, and <i>FreeGLUT</i>
will upload the object geometry there. Texture coordinates are only
generated for the teapot, teacup and teaspoon.
