* Flatten the CsgOpNodes as we build them, rather than in GetChildren * Don't inline reused nodes in CsgNode::Boolean * Reinstate difference -> union rewrite * No need for opportunistic flattening anymore * Fix typo * Remove CsgOpNode::Impl::simplified_ * Don't overskip referenced nodes in simplification * Avoid needless copy of shared pointers * Disambiguate CsgOpNode::Impl::flatten_ -> forcedToLeafNodes_ and align GetChildren arg naming * Simplified CsgOpNode::GetChildren * Simpler (a-(b+c)) -> (a-b-c) transform in CsgOpNode::Boolean to work better w/ CsgOpNode::ToLeafNode * Simpler build hints for large_scene_test.cpp * [flatten] Refine rules about tree flattening + added test case * [manifold] Propagate transforms when flattening op trees * [flatten] move tests from manifold_test to boolean_test
