  - Heavily reworked `ColorType`:
  - This type is now used for denoting formats for which we support operations
  on buffers in these memory representations. Particularly, all channels in
  - pixel types are assumed to be sized in units of bytes.
  + pixel types are assumed to be an integer number of bytes (In terms of the
  + Rust type system, these are `Sized` and one can crate slices of channel
  + values).
  - An `ExtendedColorType` (WIP: do You have better name?) is used to express
  - more generic color formats from which the library can potentially
  - convert/scale/map into a `ColorType` buffer. This operation might be
  - fallible but includes sources with 1/2/4-bit components.
  + more generic color formats for which the library has limited support but
  + can be converted/scaled/mapped into a `ColorType` buffer. This operation
  + might be fallible but, for example, includes sources with 1/2/4-bit
  + components.
  - Both types are non-exhaustive to add more formats in a minor release.
  - A work-in-progress (#1085) will further separate the color model from the
  specific channel instantiation, e.g. both `8-bit RGB` and `16-bit BGR`
