I wonder if this needs to be a new type, there is a non-trivial amount of code that has an implicit assumption that Bitmap is just a wrapper around a Buffer

Yea, if you have also looked at my previous PR (closed) for this, it involved more code change. Almost everywhere we currently return null buffer/bitmap and access it needs to be changed. So opened this one to try to have less change if possible.

Seems a good idea to be a new type for it. I will try it in the weekend.

I plan to add a BooleanBuffer type as part of #1176 which should fit this use-case
