`D3D12_HEAP_TYPE, D3D12_CPU_PAGE_PROPERTY, D3D12_MEMORY_POOL, D3D12_HEAP_FLAGS, D3D12_HEAP_PROPERTIES, and D3D12_HEAP_DESC ID3D12Heap Wrap ID3D12Device::CreateHeap Made a tricky enum because DX12 doesn't follow Rust's rules bump version to 0.2.0 Use bitflags for heap::Flags Fix typo Another typo fix
