ambient, specular, shininess for [gemwin] don't do much

[umlaeute]

Gem: v0.94_pre1-231-g279f8856

the [gemwin] helps shows ambient/specular/shininess messages in the [pd more lighting] subpatch.

it seems that those messages don't do anything (both in single-context and multi-context builds)

[ch-nry]

the message don't do anything because ambiant, specular, shininess and other are set in gemhead:

glMaterialfv(GL_FRONT_AND_BACK, GL_AMBIENT, a_color);
glMaterialfv(GL_FRONT_AND_BACK, GL_DIFFUSE, d_color);
glMaterialfv(GL_FRONT_AND_BACK, GL_EMISSION, e_color);
glMaterialfv(GL_FRONT_AND_BACK, GL_SPECULAR, s_color);
glMaterialfv(GL_FRONT_AND_BACK, GL_SHININESS, shininess);

The value are set with [ambiant], [diffuse] and other dedicated objects described in help/03.lighting/05.materials

So, I think the gemwin help is wrong and should be corrected.
