- In the annotationEditorLayer, reorder the editors in the DOM according
the position of the elements on the screen;
- add an aria-owns attribute on the "nearest" element in the text layer
which points to the added editor.
- in using the global clipboard, it'll be possible to copy from a
pdf and paste in an other one;
- it'll allow to edit a previously created annotation;
- copy the editors in the current page.
Previously, we had to set the #allowClick property by hand which was
a bit painful because it's easy to overlook one case or an other.
So with this patch a new editor (for now FreeText one only because the
Ink one is a bit different) is created on the first click if none is selected
on mousedown, else the first click will just commit the data and then the
second will creater a new editor.
The problem is clearly visible when the thickness is at max.
It's mainly because the thickness was not taken into account when
translating the div but it was when the line is drawn on the canvas.
Note that these cases, which are all in older code, were found using the [`unicorn/no-for-loop`](https://github.com/sindresorhus/eslint-plugin-unicorn/blob/main/docs/rules/no-for-loop.md) ESLint plugin rule.
However, note that I've opted not to enable this rule by default since there's still *some* cases where I do think that it makes sense to allow "regular" for-loops.
Previously it was created only on mouseover event but on a touch screen
there are no fingerover event...
The idea behind creating the ink editor on mouseover was to avoid to have
a canvas on each visible page.
So now, when the editor is created, the canvas has dimensions 1x1 and
only when the user starts drawing the dimensions are set to the page ones.
We want to avoid adding regular `id`s to xfaLayer-elements, since that means that they become "linkable" through the URL hash in a way that's not supported/intended. This could end up clashing with "named destinations", and that could easily lead to bugs; see issue 11499 and PR 11503 for some context.
Rather than using `id`s, we'll instead use a *custom* `data-element-id` attribute such that it's still possible to access the DOM-elements directly if needed. *Please note:* This is basically the xfaLayer-equivalent of PR 15057.
- and because of rounding errors it led to slightly resize again and again
the ink container;
- when zooming the size is changing but not the ratio, so in this case we
don't need to change the dimension of the container.
`HTMLSectionElement` is not part of the DOM, so the generated typescript definitions contain a non-existing type.
HTML Section elements have to be handled as simple `HTMLElements`.

[jsdoc] failing typescript builds - wrong type
Rather than including all of this external code in the PDF.js repository, we should be using the npm package instead.
Unfortunately this is slightly more complicated than you'd hope, since the `fit-curve` package (which is older) isn't directly compatible with modern JavaScript modules.
In particular, the following cases needed to be considered:
- For the development viewer (i.e. `gulp server`) and the unit-tests, we thus need to build a fitCurve-bundle that can be directly `import`ed.
- For the actual PDF.js build-targets, we can slightly reduce the sizes by depending on the "raw" `fit-curve` source-code.
- For the Node.js unit-tests, the `fit-curve` package can be used as-is.
- this way the context menu in Firefox can take into account what we
have in the clipboard, if an editor is selected, ...
- when the user will click on a context menu item, an action will be
triggered, hence this patch adds what is required to handle it;
- some tests will be added in the Firefox' patch.
Rather than forcing the user to *manually* call `setDimensions`, which is also breaking any existing third-party code, it seems that we can simply let the `AnnotationLayer.{render, update}`-methods handle that internally.
As far as I can tell, based on testing manually in the viewer *and* running the browser-tests, everything still appears to work correctly with this patch.
After the changes in PR 15036, the trigger-element created in `FileAttachmentAnnotationElement.render` is now too small. This can be fixed by using the same approach as in PR 15065, and the patch can be tested using the `annotation-fileattachment.pdf` document in the test-suite.
- for example in Dusk theme (Windows 11), black appears to be white, so
the user will draw something in white. But if they want to print or
save the used color must be black.
- fix a bug with the color input which only accepts hex string colors;
- adjust outline color of the selected/hovered editors in HCM.
- 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 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.
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.
There are obviously cases where using `concat` makes perfect sense, since that method doesn't change any of the existing Arrays; see https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/concat
However, in a few cases throughout the code-base that's not an issue and using `concat` only leads to unnecessary intermediate allocations. With modern JavaScript we can thus replace those with a combination of `push` and spread-syntax, which wasn't originally possible when the code was written.
- each annotation has its coordinates/dimensions expressed in percentage,
hence it's correctly positioned whatever the scale factor is;
- the font sizes are expressed in percentage too and the main font size
is scaled thanks a css var (--scale-factor);
- the rotation is now applied on the div annotationLayer;
- this patch improve the rendering of some strings where the glyph spacing
was not correct (it's a Firefox bug);
- it helps to simplify the code and it should slightly improve the update of
page (on zoom or rotation).

Rather than using `id`s, we'll instead use a *custom* `data-element-id` attribute such that it's still possible to access the Annotation-elements directly.
Unfortunately these changes required updating most of the integration-tests, and to reduce the amount of repeated code a couple of helper functions were added.
