cython

Considering issues like #5954 are bad to solve / debug without this information, borg should debug log full paths of all caches / indexes it uses.

Is your feature request related to a problem? Please describe.
Many static type checkers have issues finding Cython's stubs.
Here is from running mypy on my current project:

error: Skipping analyzing "cython": found module but no type hints or library stubs

The same issue can be seen when using import Cython as cython:

error: Skipping analyzing "Cython": found module but 

We don't current have a way to get the sound output through the API. This could for example be in the form of a buffer to copy at every frame.

This might also require some work to separate the sound implementation from SDL2.

rasterio.warp.reproject takes a kwargs parameter, which is passed to the "transformation function". It is not by any means clear what this means. What transformation function? What are the allowed values for kwargs? Can this please be expanded on? Thanks.

An option like $ fio cat --bounds w s e n --bounds-crs <crs> --dst-crs <crs> would allow for filtering prior to reprojection, like $ ogr2ogr -spat w s e n -spat_srs <crs>.

See Toblerity/Fiona#210 for a discussion about standardizing bounding boxes as --bounds w s e n rather than --bbox w,s,e,n.

As suggested in #264, this new functionality should be properly documented.

This could be done adding a new line in scikit-ci-yml.

The line could be

- twine check dist/*
