clang-format does nested indents for macros that dont end with ;
example:
  align_buffer_page_end(dst_y_8, dst_y_plane_size)
      align_buffer_page_end(dst_u_8, dst_uv_plane_size)
          align_buffer_page_end(dst_v_8, dst_uv_plane_size)
              align_buffer_page_end(dst_y_16, dst_y_plane_size * 2)
                  align_buffer_page_end(dst_u_16, dst_uv_plane_size * 2)
                      align_buffer_page_end(dst_v_16, dst_uv_plane_size * 2)

use a similar allocator to the one used within libyuv in row.h which makes the caller add ;
  align_buffer_page_end(dst_y_8, dst_y_plane_size);
  align_buffer_page_end(dst_u_8, dst_uv_plane_size);
  align_buffer_page_end(dst_v_8, dst_uv_plane_size);
  align_buffer_page_end(dst_y_16, dst_y_plane_size * 2);
  align_buffer_page_end(dst_u_16, dst_uv_plane_size * 2);
  align_buffer_page_end(dst_v_16, dst_uv_plane_size * 2);
