Meshes: Make object mesh face shading consistent

Browse Source 
Previously, object meshes had their North and South faces darker than
East and West faces, the opposite of nodes and meshnodes. This commit
corrects this.
State constants as float-literals not double-literals.
Simplify code.
Add comment.
