The idea is to have a horizontal pattern split into two with the top and
bottom halves having different precision. This allows one to see whether
10bpc support is working properly or not, as there are many pieces to
the puzzle beyond the basic format support (gamma ramps, bpc encodings,
etc).
This is really only useful on 10bpc formats, but we also add support for
8bpc formats to ease testing. In the future, this could be applied to
16bpc formats as well.

This also adds a helper to generate a color LUT, which has to be used in
conjunction with the C8 indexed format.

Some of the helpers, such as the pattern drawing helpers or the format
lookup helpers, have potential to be reused. Move them into a separate
library to make it easier to share them.
