Fixed cracks in MMU painting gizmo. All triangles, even not painted triangles, are now rendered inside MMU painting gizmo.

Browse source 
The cracks were caused by using glPolygonOffset to resolve Z-fighting. All triangles of the object were firstly rendered entirely with a base color. And then paint triangles were drawn over these already rendered triangles.
