 Times are one 1920 x 1080 RGB frame end to end (`submit` to `wait_view`, with
 the DN image ready to read), median of criterion runs, over models from 12 to

-on the Intel Core Ultra 9 285K's 24 cores. Run to run, the RTX 3060's times
-vary by about 5 %, and lavapipe's by up to 15 % between sessions. The sample is the Landsat 8 example scene

-L1 adds Earth's surface, shadows on the target, Earthshine and Moonshine,
-the Moon's albedo map and phase curve, the Sun's limb darkening and eclipses
-seen on Earth and the Moon; its row comes with its measurements. Planned: C1
-and C2 add pixel-area sampling, lens distortion, blur and detector noise; L2
-adds measured materials and the atmosphere; L3 is path traced.

 - `--out` writes raw DN as a 16-bit PNG, shifted up to fill 16 bits as
   cameras usually store them: a 12-bit DN is the stored value divided by 16.
   It is linear, so it looks dark next to the preview.
