How to apply Matcap materials for sculpting in Blender 2.71? I'm following the instructions found in Ben Simonds' "Blender Master Class" and both the Materials and Textures interfaces seem to have changed significantly since the book was written.  I'm supposed to make the material Shadeless, to set the texture's Image or Movie to Normal which is supposed to be under the "Mapping Tab", and in the Display Panel of the 3D View I'm supposed to set the shading option to GLSL.  While all this (mostly) makes sense to me, I just can't find any of these settings anywhere.
Note also that you must be in "Solid" view mode to see the matcap option under the N menu. This seems obvious to me now, but I've been all over the internet trying to find out why I don't see the Matcap option everyone else has. :)
