Karam expects the config to be of type `Config`. This can be done by calling the karma.config.parseConfig method which creates a Config object that can be passed to karma.Server()

By nulling the `annotations` config var, the direct link fragment no longer affects annotations shown in the notebook.

Add back horizontal-rhythm util styles, but use a different alignment
technique for a child element to assure that timestamps align right in
annotation cards.

Remove an unneeded horizontal-rhythm mixin from AnnotationHeader. Fixes
a regression in which the timestamps were not appearing right-aligned
in the header of annotation cards.

* Move logic for adding a new, unsaved page note to AnnotationsService
* Render new-note button as a `LabeledButton` within `SelectionTabs`
* Remove `NewNoteBtn` component

To apply theming from settings, we need to be able to set inline styles
on buttons.

Use a simpler mixin for Notebook's "inner" container: we don't need
all the stuff in `panel`, `card-frame` suffices. This eliminates the
need to override a vertical rhythm rule.

This is the first time in my life I've ever found what seems like a
potentially valid use case for `!important`: assuring that a utility
class that establishes rhythm based on margins is able to do its job.

Typically, our components should not be styling their own margins, but
there are some cases where we do, e.g. the initial reset of button
styles, which sets `margin: 0`. (Components should style their own
padding, but margins are the domain of containing/parent elements).

These two `!important` rules allow two utility mixins that are explicitly
concerned with margins to trump the specificity of margin-resetting
rules on descendent elements.

This PR makes the adder to reposition when the adder is visible and the
window is resized. In this way the adder is always close to the selected
text.

Closes #3194

Use the `ListenerCollection` utility to register and unregister
listener, similarly to other parts of the application.

Add sidebar-wide custom styling for "compact" icon buttons: icon-only
buttons with no touch-input min-size and tighter padding, as used in
the `TopBar`

Update components to use `IconButton` with `CompactIconButton` styling
where applicable.

* Labeled buttons should continue sizing font as 1em, icons default at
  1.25em (no change)
* Icon-only buttons should size icon at 1em (instead of 1.25em) because
  the icon _is_ the content

Update `AnnotationActionBar` to set local font size to 16px to get
desired icon sizing (@1em).

This will allow elements to set contextual 1em=16px for appropriate
icon sizing (in buttons)

`GroupListItem` and `GroupListSection` are never used outside of the
`GroupList` itself.

When the selection of text finishes on the sidebar's iframe, the click
event is not fired. Hence, the sidebar is not collapsed and the adder is
not displayed. This is because events don't bubble up through the
iframe.

This PR makes the sidebar to collapse on 'mousedown' events on the host
page. This is similar in nature to the 'touchstart' event that guest
already listens (although for a different reason).

Closes #463

Make sure all buttons—including icon-only buttons—get a flex layout. For
icon-only buttons, this ensures that the icon is centered on the button,
which is relevant especially when a `min-width` or `min-height` is
applied.

The term "plugin" is vestigial. The remaining cross-frame.js module in this
directory has been moved up to the top level of `src/annotator/` since
there isn't a more specific home that is suitable. Also change the
`CrossFrame` class to be a named rather than default export per current
conventions.

Move `RenderingStates` enum from `pdfjs-rendering-states.js` to
`src/annotator/anchoring/pdf`.

This is part of an exercise to declutter the root of src/annotator.
