command: change properties added in previous commit

Make their meaning more exact, and don't pretend that there's a
reasonable definition for "bits-per-pixel". Also make unset fields
unavailable.

average_depth still might be inconsistent: for example, 10 bit 4:2:0 is
identified as 24 bits, but RGB 4:4:4 as 12 bits. So YUV formats
seemingly drop the per-component padding, while RGB formats do not.
Internally it's consistent though: 10 bit YUV components are read as
16 bit, and the padding must be 0 (it's basically like an odd fixed-
point representation, rather than a bitfield).
