The bit-placement of samples within a texel.

We start with low-order bits in a little-endian representation of the surrounding numbers. So, for example, Int332 has the first sample in the three lowest bits of a u8 (byte-order independent) and a Int565 has its first channel in the first 5 low-order bits of a u16 little endian interpretation of the bytes.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
