This method is usually used with loops, and it should be a tiny bit more efficient to use an iterator directly rather than first iterating through ` Map`-values to create a temporary `Array` that we finally iterate through at the call-site.
Note that the `getRawValues` method is old code, and originally the `Dict` class stored its data in a regular `Object`, hence why the old code was written that way.

- Add a new test using only streaming, since that was missing and the lack of which most likely contributed to previous bugs in the `PDFDataRangeTransport` implementation (see PR 10675 and 20634).
- Improve the "ranges and streaming" test, to utilize both ranges *and* streaming properly, since the way it was written seemed somewhat unrealistic given how data will normally arrive when `PDFDataRangeTransport` is being used.
- Provide more `initialData`, in relevant tests, since a length smaller than `rangeChunkSize` seem pretty pointless.
- Test the `contentDispositionFilename`, and `contentLength`, handling in the `PDFDataRangeTransport` implementation.
This behaviour comes from the initial pdf.js commit but is wrong and
doesn't match other PDF readers like muPDF or pdfium.
From PDF Spec 7.3.3:
A PDF writer shall not use the PostScript language syntax for numbers with non-decimal radices (such
as 16#FFFE) or in exponential format (such as 6.02E23).
It fixes#20715.
`failedExpectations` was removed from `suiteStarted` and `specStarted` events.
HtmlReporter and HtmlSpecFilter have been deprecated and removed.
Change all these cases to use `Map.prototype.getOrInsertComputed()` instead, in combination with a helper function for creating the `Array`s (similar to the previous patch).
With the exception of the first invocation the callback function is unused, which means that a lot of pointless functions may be created.
To avoid this we introduce helper functions for simple cases, such as creating `Map`s and `Objects`s.
In all cases where we currently use `Response.prototype.arrayBuffer()` the result is immediately wrapped in a `Uint8Array`, which can be avoided by instead using the newer `Response.prototype.bytes()` method; see https://developer.mozilla.org/en-US/docs/Web/API/Response/bytes
Report loading progress "automatically" when using the `PDFDataTransportStream` class, and remove the `PDFDataRangeTransport.prototype.onDataProgress` method
Currently this code expects a "url string", rather than a proper `URL` instance, which seems completely unnecessary now. The explanation for this is, as so often is the case, "historical reasons" since a lot of this code predates the general availability of `URL`.
This is consistent with the other `BasePDFStream` implementations, and simplifies the API surface of the `PDFDataRangeTransport` class (note the changes in the viewer).
Given that the `onDataProgress` method was changed to a no-op this won't affect third-party users, assuming there even are any since this code was written specifically for the Firefox PDF Viewer.
This should help reduce the maintenance burden of the code, since you no longer need to remember to update separate code when touching the different page/thumbnail classes.
The percentage calculation is currently "spread out" across various viewer functionality, which we can avoid by having the API handle that instead.
Also, remove the `this.#lastProgress` special-case[1] and just register a "normal" `fullReader.onProgress` callback unconditionally. Once `headersReady` is resolved the callback can simply be removed when not needed, since the "worst" thing that could theoretically happen is that the loadingBar (in the viewer) updates sooner this way. In practice though, since `fullReader.read` cannot return data until `headersReady` is resolved, this change is not actually observable in the API.

[1] This was added in PR 8617, close to a decade ago, but it's not obvious to me that it was ever necessary to implement it that way.
Given that there's no less than *five* different, but very similar, implementations this helps reduce code duplication and simplifies maintenance.
Also, remove the `rangeChunkSize` not defined checks in all the relevant stream-constructor implementations.
Note how the API, since some time, always validates *and* provides that parameter when creating a `BasePDFStreamReader`-instance.
Given that there's no less than *five* different, but very similar, implementations this helps reduce code duplication and simplifies maintenance.
Also, spotted during rebasing, pass the `enableHWA` option "correctly" (i.e. as part of the existing `transportParams`) to the `WorkerTransport`-class to keep the constructor simpler.
Modified the regex in web/autolinker.js to explicitly allow hyphens (-) in
the domain part of email addresses, while maintaining the exclusion of
other punctuation. This fixes mailto links like user@uni-city.tld being
truncated at the hyphen.
Fixes#20557
Usually, content stream or fonts are compressed using FlateDecode.
So use the DecompressionStream API to decompress those streams
in the async code path.
Update the styles and HTML to reflect the new views manager concept.
For now, nothing about split/merge functionality is implemented or visible.
The new styles for the outline, attachments, and layers will be added later.
The thumbnail view is now accessible with the keyboard.
This commit moves all the logic to scale up&down `<span>`s in the text
layer, introduced in #18283, to CSS.
The motivation for this change is that #18283 is still not enough for
all cases. That PR fixed the problem in Chrome&Firefox desktop, which
allow users to set an actual minimum font size in the browser settings.
However, other browsers (e.g. the Chrome-based WebView on Android) have
more complex logic and they scale up small text rather than simply
applying a minimum.
A workaround for that behavior is probably out of scope for PDF.js
itself as it only affects not officially supported platforms. However,
having access to the actual expected font height (through
`--font-height`) allows embedders of PDF.js to implement a workaround by
themselves.
The linter found some issues in viewer.html with </input> which isn't required
and a missing closing div in test/resources/reftest-analyzer.html.
The HTML can now be nicely formatted. In order to not break the build for
mozilla-central, the preprocessor has been fixed in order to take into account
the white spaces at the beginning of a comment line.
And finally, make .prettierrc (which is supposed to be either json or yaml)
itself lintable.
For now it's just possible to create a single pdf in selecting some pages in different pdf sources.
The merge is for now pretty basic (it's why it's still a WIP) none of these data are merged for now:
- the struct trees
- the page labels
- the outlines
- named destinations
For there are 2 new ref tests where some new pdfs are created: one with some extracted pages and an other
one (encrypted) which is just rewritten.
The ref images are generated from the original pdfs in selecting the page we want and the new images are
taken from the generated pdfs.
