Mesh_PrimitiveMode is missing some tests along Points and Lines

[stevk]

• We need more points so that the model is visible. Outline a square with 16 points (Whatever fits on two lines)? All have the same normal.

• Add points with normals. W/o indices. With Texture coords

• Add Lines w normals

• Add lines with normals, tangent, normal tex. With Texture coords

Consider grouping all of the extra stuff into one column if things get too wide.
