kicad-source/3d-viewer/3d_draw.cpp
unknown d40ea8adcb 3D viewer: fix issues with transparencies in some models (material issues in VRML2 parser) 
Fix some issues in filling zones normals.
Fix an issue with some models that have materials but didn't defined the diffuse color.
Workaround for Bug #1443431.
Implement some missing "code logic" for pervertexperface normals.
Remove some not used functions.
Calculate normals using double type.
