Subject: [PATCH] dozen: Increase optimalBufferCopy*Alignment

D3D12 requires the offset to be 512B-aligned and row pitch to be
256B-aligned for copy commands.  There will need to be a fallback
written eventually because Vulkan has no such requirements but these
will remain the optimal limits as they allow using the D3D12 copy
commands directly.
