- Most of the these are only used in the `src/display/api.js` file, and this leads to slightly shorter code.
- A number of unit-tests need a `BaseCanvasFactory`-instance, however that one is available through the `PDFDocumentProxy`-instance nowadays.
- For other unit-tests the remaining necessary default Factory-definitions can be moved into the `test/unit/test_utils.js` file.
This prepares for a future where we're using more than one wasm-file, originating in different `external/`-folders, by extending the existing `gulp.watch` usage.

Rather than waiting for the upstream patch to reach the Firefox version we're using with Puppeteer, let's just set the same preference as done in https://phabricator.services.mozilla.com/D234320.
Currently we're not checking that the response is actually OK before getting the data, which means that rather than throwing an error we can get an empty `ArrayBuffer`.
To avoid duplicating code we can move an existing helper into `src/core/core_utils.js` and re-use it when fetching the JPX wasm-file as well.
Given that we nowadays provide default Node.js versions of these Factory-parameters it no longer seems necessary to mention that environment specifically.
These old exceptions have a fair amount of overlap given how/where they are being used, which is likely because they were introduced at different points in time, hence we can shorten and simplify the code by replacing them with a more general `ResponseException` instead.
Besides an error message, the new `ResponseException` instances also include:
- A numeric `status` field containing the server response status, similar to the old `UnexpectedResponseException`.
- A boolean `missing` field, to allow easily detecting the situations where `MissingPDFException` was previously thrown.
In order to fix bug 1935076, we'll have to add a pure js fallback in case wasm is disabled
or simd isn't supported. Unfortunately, this fallback will take some space.
So, the main goal of this patch is to reduce the overall size (by ~93k).
As a side effect, it should make easier to use an other wasm file (which must export
_jp2_decode, _malloc and _free).
When a dash separates two digits, it's very likely to not be a hyphen
inserted to split a word into two lines (e.g. "par\n-ser"), but rather
either a minus sign, a range, or a date. For example, in the tracemonkey
PDF there is `2008-02` (a date) split across two lines.
Preserving the dash, similarly to how we do for compound words, allows
searches for "2008-02" to find a match.
In Firefox, double-clicking on a stamp annotation triggers text
selection (selecting the last text element in the dom before the
annotation): this triggers the logic to make annotations not interfere
with text selection, which in turns prevents the double click from
triggering the annotation editor.
This commit fixes the problem by making annotations non-selectable, so
that clicking on them does not trigger text selection. Freetext
annotations were already non-selectable, so this commit doesn't change
that. However, we need to explicitly mark text in popups as selectable.
In the affected font the total number of mapping-entries is `1142348`, and no less than `997473` of them are duplicates.
Given that every duplicate causes a lot of Array elements to be moved this becomes extremely inefficient, which we can avoid by keeping track of seen `charCode`s and directly build the final mappings-Array instead.
Currently we re-implement a number of helper functions specifically for this code, which seems completely unnecessary since there's already general purpose ones available in the `src/core/core_utils.js` file.
It lets the user make a pinch gesture with a finger on page with a drawing
and the second finger on an other page.
On mobile, it's pretty easy to be in such a situation.
It fixes#19239.
When the canvas isn't existing the editor has no image: it's fine because the editor is invisible.
Once it's made visible, the canvas is set when the annotation layer has been rendered.
This appears to have regressed in PR 13808, since it removed the `matrix`-entry from array returned by the `MeshShading.prototype.getIR` method *without* also updating the indexes in the `MeshShadingPattern` constructor.
Reasons for removal:
- These tests never generated any warnings from OSS-Fuzz, in over a year.
- An error thrown during image decoding will lead to a broken/missing image, not a security problem.
- These tests rely on the Jazzer.js library, which has a number of problems: It now causes failures in Node.js v23 in the CI tests, it's no longer being maintained upstream, and it lacks support for some (fairly common) CPU architectures.
