docs: Returns an ordered series of scaled resources to try when loading an asset. The native
  resolution will be tried first, then that will be rounded up to the nearest whole integer and
  stepped down through all whole integers to {@code 1}. If the native scale factor is {@code 2},
  this will yield {@code 2, 1}. If the native scale factor is {@code 4}, this will yield
  {@code 4, 3, 2, 1}. Android devices often have fractional scale factors, which demonstrates
  the rounding up then back down approach: a native scale factor of {@code 2.5} would yield
  {@code 2.5, 3, 2, 1}.
