How to display a bitmap object?

[bredej]

The bitmap could for instance be received from a network connection or be the result of some image processing.
I don't see how I can update a pixmap surface from an in-memory object.

There is no option with the current cairo backend (although it is easy to add if you care to submit a PR). The artist port (skia_2024 branch) does have this option: https://github.com/cycfi/artist/blob/master/lib/include/artist/image.hpp#L112-L132

A PR would be great! Ideally, both branches should have the same API. Work in progress, but contributions are VERY welcome.
