# Description

For all observation-related terms, we follow the noun name for the
function. However, the camera one was called `grab_images`. This MR
renames it to `image` to make it consistent with the others.

Also the docstring for the math-utils were messed up. According to
Google's docstyle, the first line should be a short summary and a
detailed summary should move to the next paragraph. This MR fixes that
as well.

Lastly, the name of the function
`convert_perspective_depth_to_orthoginal_depth` has too much redundancy.
The MR renames it to `orthogonalize_perpsective_depth`.

All these are breaking changes with no backwards compatibility (since
they were added post-last release anyway).
