This required a small change in `FilterStatus` to enable TS to better understand
the shape of `buttonProps` depending on which code branch is taken.

In particular clarify that references to `annotation` refer to an object
with only ID properties and not the whole annotation object.

This found apparent missing checks for a null `profile.userid` (ie. current user
is logged out) in several places. These places should not be reachable
when the user is logged out due to checks elsewhere, but add explicit
checks for the user being logged in.

Adapt to current naming conventions for identifiers.

Use shared `TextInput` component for presentational consistency.

Adjust styling of buttons and link in markdown editor toolbar to better
handle touch interfaces and focus rings.

Also fix casing in `classnames` import.

This warning is useful to detect situations where the page text and text layer
differ beyond just whitespace differences, which will result in
misalignment of highlights.

Re-use this utility to translate offsets between the original page text
and the whitespace-stripped version of the page text. This allows the
`stripSpaces` helper to be simplified and avoids creating some offset
arrays that are unused.

These arose from resolving confusion during a verbal code review.

Expand on the choice of "input" and "output" as names for the two string
arguments. These could equally have been "source" and "destination" or
"stringA" and "stringB".

When anchoring a quote in a PDF, the quote is first searched in text
extracted using PDF.js's `PDFPage.getTextContent` API, and the resulting
positions are used to create a range within the hidden text layer of a
page.

An issue we've seen several times when doing PDF.js upgrades is minor
changes to which spaces are included in the text layer. In the past
we've adapted our text extraction to match the text layer each time.
This slows down the process of upgrading PDF.js and makes maintaining
compatibility with a range of PDF.js releases more difficult. In the
most recent update, an `includeMarkedContent` option was added to the
`getTextContent` API, and the presence of that option could affect
whether certain whitespaces are included in the output nor not [1].

Try to address this issue generally by mapping offsets from the page
text into offsets in the text layer in a way that ignores whitespace
differences.

 - Add `translateOffsets` utility, which maps a (start, end) pair
   of offsets in an input string into corresponding offsets in an output
   string, where the output is a version of the input that has been
   "corrupted" by the addition or removal of certain characters (eg.
   whitespace)

 - Use `translateOffsets` utility in PDF anchoring to map quote offsets
   in the page text returned by `PDFPage.getTextContent` into offsets in
   the `textContent` of the text layer element.

Remove "is" from some state-related reference names.

This separates out the component styling from the contextual/positioning
styling.

Fade the Spinner in slowly on annotation-save such that it only appears
if saving the annotation is taking a while. This reduces visual clutter
when the annotation saves quickly.

Fix height-jumping issue with saving message in Annotation
