This replaces the boolean `annotationEditorEnabled` option/preference with a "proper" `annotationEditorMode` one. This way it's not only possible for the user to control if Editing is enabled/disabled, but also which *specific* Editing-mode should become enabled upon PDF document load.
Given that Editing is not enabled/released yet, I cannot imagine that changing the name and type of the option/preference should be an issue.
Note that even though Puppeteer got a major version bump the changelog
doesn't include compatibility changes that are relevant to us; please
see https://github.com/puppeteer/puppeteer/releases.
Currently we're loading the `web/annotation_layer_builder.css` and `web/xfa_layer_builder.css` files *directly* during the reference tests.
This becomes a problem is we want to reduce duplication in the CSS-files, e.g. by placing *common* rules in the `web/pdf_viewer.css` file.
Given that `gulp components` is already being utilized when running tests, we can thus use that to instead depend on the *entire* viewer-components CSS-file in the reference tests.
Similar to other recent patches, see e.g. PR 15057, we don't want to add these kind of `id`s to DOM-elements since they shouldn't become "linkable" through the URL hash.
*Please note:* This patch can be tested, in the viewer, with e.g. `bug1737260.pdf` from the test-suite.
- As in the annotation layer, use percent instead of pixels as unit;
- handle the rotation of the editor layer in allowing editing when rotation
angle is not zero;
- the different editors are rotated counterclockwise in order to be usable
when the main page is itself rotated;
- add support for saving/printing rotated editors.
Given that Annotations can also have an `OC`-entry, we need to take that into account when generating their operatorLists.
Note that in order to simplify the patch the `getOperatorList`-methods, for the Annotation-classes, were converted to be `async`.
- the annotations must be rendered in the same order as the chronological one.
- fix a bug in document.js which avoids to read a saved pdf correctly in Acrobat:
there is no need to reset the xref state: it's done in worker.js once everything
has been saved.
Given that printing is triggered *synchronously* in browsers, it's thus possible for scripting (in PDF documents) to modify the Annotation-data while printing is currently ongoing.
To work-around that we add a new printing-specific `AnnotationStorage`, where the serializable data is *frozen* upon initialization, which the viewer can thus create/utilize during printing.
For encrypted PDF documents without the required permissions set, this patch adds support for disabling of Annotation-editing. However, please note that it also requires that the `pdfjs.enablePermissions` preference is set to `true` (since PDF document permissions could be seen as user hostile).[1]
As I started looking at the issue, it soon became clear that *only* trying to fix the issue without slightly re-factor the surrounding code would be somewhat difficult.
The following is an overview of the changes in this patch; sorry about the size/scope of this!
- Use a new `AnnotationEditorUIManager`-instance *for each* PDF document opened in the GENERIC viewer, to prevent user-added Annotations from "leaking" from one document into the next.
- Re-factor the `BaseViewer.#initializePermissions`-method, to simplify handling of temporarily disabled modes (e.g. for both Annotation-rendering and Annotation-editing).
- When editing is enabled, let the Editor-buttons be `disabled` until the document has loaded. This way we avoid the buttons becoming clickable temporarily, for PDF documents that use permissions.
- Slightly re-factor how the Editor-buttons are shown/hidden in the viewer, and reset the toolbar-state when a new PDF document is opened.
- Flip the order of the Editor-buttons and the pre-exising toolbarButtons in the "toolbarViewerRight"-div. (To help reduce the size, a little bit, for the PR that adds new Editor-toolbars.)
- Enable editing by default in the development viewer, i.e. `gulp server`, since having to (repeatedly) do that manually becomes annoying after a while.
- Finally, support disabling of editing when `pdfjs.enablePermissions` is set; fixes issue 15049.

Note how the "page"-div, "canvasWrapper"-div, and `textLayer`-div all have *integer* dimensions (rounded down) rather than using the "raw" viewport-dimensions.
Hence it seems reasonable that the same should apply to the "annotationLayer"-div, now that it's explicit dimensions set.
