Given how recently logical assignment operators support were added to browsers, we're intentionally translating them even in `SKIP_BABEL = true` builds for the time being.
However, in either `MOZCENTRAL` or `TESTING` builds it should be OK to simply leave logical assignment operators intact.
With the changes in PR 12831, it's no longer necessary to keep track of the `fontName`-string separately since it's available through the `_defaultAppearanceData`-property as well.
* Add a parser to get font data from the default appearance
- pdfium & poppler use a special parser too to get these info.
* Update src/core/default_appearance.js

This adds "optional chaining" and "nullish coalescing" to the list of features needed when using the *modern*, i.e. non-translated/non-polyfilled, build of the PDF.js library.
- Don't explicitly mention "ES5" in https://mozilla.github.io/pdf.js/getting_started/#download, since that's no longer accurate. As-is, this will more than likely give users the wrong impression regarding our *actual* browser support.
- Reword the "Getting the Code"-section of the README, since an ES6-compatible browser is no longer sufficient for development purposes given our usage of modern ECMAScript features.
- Update the "Building PDF.js"-section of the README, to explicitly mention both the `gulp generic` and `gulp generic-es5` commands.
Hopefully this will help reduce *some* user confusion, but we should perhaps also consider changing the "-es5"-suffix in our build-scripts and build-folders. (That would however require coming up with a "better" suffix, which might not be trivial.)
The whole purpose of showing a notification on the `sidebarToggle` button, when the sidebar is closed, was to give users *some* kind of indication that the PDF document contains outline/attachments/layers without having to manually open the sidebar to check.
However, in the implementation in PR 7959, I also added notifications for each view-buttons in the sidebar. Looking back at this, I've always questioned the value of the last part, since the view-buttons already have a `disabled`-state which shows if they're available or not. Hence we're actually, in a sense, duplicating notifications for the outline/attachments/layers-buttons without adding (in my opinion) all that much overall value.
All-in-all, I'm thus proposing that we only display the notification on the `sidebarToggle`-button itself, since that should really be sufficient here, which also allows us to simplify the relevant code a fair bit.
- aims to fix issue #12868: apply zoom factor to linewidth after setting it to 1.
- only apply 1px-width when required
- the sign of getSinglePixelWidth is used to know if 1px-width is required
- Remove a *duplicated* reference test, see "issue12810", from the manifest.
- Improve the spelling in a couple of comments in `src/core/canvas.js`, most notable of the word "parallelogram".
- Update a comment, also in `src/core/canvas.js`, to actually agree with the value used to reduce confusion when reading the code.
While PR 12725 fixed bug 1671312 as reported, i.e. the "In the upper right corner "Purposes' has bad kerning."-part, it however broke other parts of the text rendering.
Note in particular the tables, e.g. on page 2 and beyond, where the glyphs are now rendered too close together. The reason for this is that the fonts in question are non-embedded ArialNarrow, which we just replace with Helvetica which obviously is not narrow. Given that the font replacement isn't a perfect fit for non-embedded ArialNarrow, we still need to re-measure the glyph widths in this case.
Note first of all how the `PDFDocumentProxy.getJSActions` method in the API caches the result, which makes repeated lookups cheap enough to not really be an issue.
Secondly, with the previous patch, we're now only dispatching "pageopen"/"pageclose"-events when there's actually a sandbox that listens for them.
All-in-all, with these changes we can thus simplify the default-viewer "pageopen"-event handler a fair bit.
This patch is a rebased *and* refactored version of PR 9448, such that it applies cleanly given that `PDFFindController` has changed since that PR was opened; obviously keeping the original author information intact.
This patch will thus ensure that e.g. fractions, and other things that we normalize before searching, will still be highlighted correctly in the textLayer.
Furthermore, this patch also adds basic unit-tests for this functionality.
*Note:* The `[api-minor]` tag is added, since third-party implementations of the `PDFFindController` must now always use the `pageMatchesLength` property to get accurate length information (see the `web/text_layer_builder.js` changes).

The "pageopen"/"pageclose"-events are only necessary if, and only if, there's actually a sandbox to dispatch the events in. Hence we shouldn't dispatch those events unconditionally, as soon as `enableScripting` is set, but rather initialize that functionality only when needed.
Furthermore, in `web/app.js`, there's currently a bug since we're attempting to *manually* simulate a "pageopen"-event for a page that may not actually have been rendered at the time. With the modified `BaseViewer.initializeScriptingEvents` method, we'll now dispatch a correct "pageopen"-event here.
Not only was long text in popups no longer wrapped correctly, the
alignment was also center instead of left (or right, depending on the
locale used) for both text in popups and the other parts within the
annotation's section, such as the icon.
* add a comment to explain how minimal linewidth is computed.
* when context.linewidth < 1 after transform, firefox and chrome
don't render in the same way (issue #12810).
* set lineWidth to 1 after transform and before stroking
- aims fix issue #12295
- a pixel can be transformed into a rectangle with both heights < 1.
A single rescale leads to a rectangle with dim equals to 1 and
the other to something greater than 1.
* change the way to render rectangle with null dimensions:
- right now we rely on the lineWidth set before "re" but
it can be set after "re" and before "S" and in this case the rendering
will be wrong.
- render such rectangles as a single line.
Note that these changes were done automatically, using `gulp lint --fix`.
With this rule, we'll thus enforce a *consistent* formatting of zero-lengths in our CSS files.

With the updated default viewer UI, some `dir`-dependent CSS rules are now redundant since *identical* rules are being specified for both LTR and RTL mode; after PR 12807 landed I've found even more of these cases.
Note in particular that the findbar-button rules can be simplified quite a bit, since there's a fair amount of unnecessary duplication in the CSS.
