* `Face4` now supports `MeshBitmapUVMappingMaterial` * Changed order of `*StrokeMaterial` parameters. Now it's `color`, `opacity`, `lineWidth`. * `BitmapUVMappingMaterial` > `MeshBitmapUVMappingMaterial` * `ColorFillMaterial` > `MeshColorFillMaterial` * `ColorStrokeMaterial` > `MeshColorStrokeMaterial` * `FaceColorFillMaterial` > `MeshFaceColorFillMaterial` * `FaceColorStrokeMaterial` > `MeshFaceColorStrokeMaterial` * `ColorStrokeMaterial` > `LineColorMaterial` * `Rectangle.instersects` returned false with rectangles with 0px witdh or height
