Fixes

• GLTF tests now run on Windows
• GLTF can now resolve file:// protocol on windows

Breaking Changes

• drawing/coloring.MultiplyRGBByConstant renamed to drawing/coloring.ScaleColor
• GLTF
  • GLTF reader and writer now maintain parent-child relationship of nodes when translating to Polyform's version of models, instead of flattening them.
  • GLTF writer Instancing Strategy has been hiked up from the scene to the writer itself.
  • gltf.Parse has been renamed to gltf.ParseGLTF
  • gltf.Load has been renamed to gltf.LoadGLTF (you can use LoadFile to be format independent)
