When there are *multiple* empty glyphs at the start of the data, ensure that the "first" glyph gets a correct `endOffset` to avoid skipping it during parsing in the `sanitizeGlyph` function.
The situation described in issue 14626 seems like a fairly special case, and it thus seem reasonable that we simply follow the same pattern as elsewhere in the `PartialEvaluator` when the `stopAtErrors` API-option is being used.
Unfortunately simply using `appearance: textfield;`, or even `-webkit-appearance: textfield;`, doesn't actually hide the "spinner" in number-input elements in e.g. Google Chrome.
Hence we need to use a work-around with the `-webkit-inner-spin-button` rule, however in our CSS code we also have `-webkit-outer-spin-button` currently. According to both [the MDN compatibility data](https://developer.mozilla.org/en-US/docs/Web/CSS/::-webkit-outer-spin-button#browser_compatibility) and also manual testing in Google Chrome Beta 99, the `-webkit-outer-spin-button` rule is no longer necessary and we can thus clean-up the CSS a tiny bit.
This was added in PR 4516 specifically for Safari on iOS devices, but according to MDN it should no longer be necessary now; see https://developer.mozilla.org/en-US/docs/Web/CSS/-webkit-overflow-scrolling#browser_compatibility
According to the MDN compatibility data, this CSS feature:
- Was never implemented anywhere *except* for Safari on iOS.
- Was never standardized and thus never existed in an *unprefixed* version.
- Has now been removed, starting with Safari version 13.
Given that [the FAQ](https://github.com/mozilla/pdf.js/wiki/Frequently-Asked-Questions#faq-support) already lists Safari as "Mostly" supported, and that the default viewer is written primarily for Mozilla Firefox, it ought to be fine to remove these CSS rules now.
Since the Autoprefixer plugin indirectly depends on this, it seems like a good idea to add this as a direct dependency in the PDF.js project to hopefully avoid having to manually update `caniuse-lite` in the future; see https://github.com/browserslist/browserslist#browsers-data-updating
Also, slightly tweaks the Autoprefixer config for GENERIC-builds of the PDF.js library; note that this change doesn't affect the contents of the *built* `web/viewer.js` file.
The "External: Promise"-page in the JSDocs pre-dates the introduction of `Promise`s, as a generally available standard JS feature, by a number of years. Hence it now longer seems necessary, as far as I can tell, to include this "special" page in the documentation.
Also, while unrelated to the rest of the patch, updates the `test/`-folder description in the documentation.
The call-sites are replaced by direct `typeof`-checks instead, which removes unnecessary function calls. Note that in the `src/`-folder we already had more `typeof`-cases than `isString`-calls.
This removes the `DocumentInfoValidators` structure, and thus (slightly) simplifies the code overall. With these changes we only have to iterate through, and validate, the actually available Dictionary entries.
- Scroll the selected reference into view (makes it easier to tell which pdf you're looking at)
- Show the keyboard shortcuts (easier for new people)
- Keep the test/ref controls visible (if you scroll you can now tell if you're looking at a test or ref)
Sometimes I get a "Unable to find target with id XXX closeTarget..." error
when running tests which happens when test.js tries to close all the
open pages. I haven't been able to fully verify since this is intermittent,
but I think this is coming from us closing the window in driver.js and also
trying to close it in test.js.

- previously we were trying to adjust lineWidth to have something correct after the current transform is applied but this approach was not correct because finally the pixel is rescaled with the same factors in both directions.
And sometimes those factors must be different (see bug 1753075).
- So the idea of this patch is to apply a scale matrix to the current transform just before setting lineWidth and stroking. This scale matrix is computed in order to ensure that after transform, a pixel will have its two thickness greater than 1.
All call-sites that use `wrapReason` should be passing a (possibly cloned) `Error` to the helper function, hence we shouldn't need to have a fallback code-path for any other data.
Note that for the `cancel`/`error` methods on Streams, since PR 11115 we've been asserting that the argument is in fact an `Error` as intended.
When calling `wrapReason` from *rejected* Promises, we should also be guaranteed that an `Error` is provided thanks to the ESLint rules `no-throw-literal` and `prefer-promise-reject-errors`.
