Add a generic crypto.Hash template function returning the hex-encoded
checksum of a string using one of md5, sha1, sha256 (default), sha384 or
sha512. The supported algorithms match those used for the SRI hash in
.Data.Integrity on fingerprinted resources, so an SRI hash can be built
by composing with encoding.HexDecode and encoding.Base64Encode.

The encode/decode is implemented in a WebAssembly module built from a
small C wrapper around libavif. Bundled libraries (statically linked,
compiled with the WASI SDK):
* libavif v1.4.1 (container + codec glue)
* libaom v3.14.1 (AV1 encoder + decoder)
* dav1d 1.5.3 (AV1 decoder)
* libyuv (Chromium pin) for color conversion
* parson for JSON message passing across the wasm boundary
HDR handling on the encoder:
* SDR images are written as BT.709 / sRGB / BT.601 (8-bit).
* 10-bit and up are written as BT.2020 primaries with PQ (SMPTE
ST 2084) transfer and BT.2020-NCL matrix coefficients, signalled
via CICP.
* Adobe-style SDR+gainmap inputs (e.g. Lightroom HDR exports) are
baked into a single true-HDR image in BT.2020/PQ at 10-bit, with
the CLLI (Content Light Level Information) box carried through so
HDR-capable clients can tone-map correctly.
Limitations:
* Animated input (animated WebP/GIF) is collapsed to its first frame
when re-encoded as AVIF; animated AVIF output is not yet supported.
Fixes#7837
Fixes an issue where improper attribute derivation from the page's
relative permalink caused failures with `outdir`, `imagesoutdir`, and
`imagesdir` when `markup.asciidocext.workingFolderCurrent` is enabled.
The updated logic now correctly handles:
- Multi-byte characters
- Multilingual multi-host sites
- Site builds from a subdirectory
- Pages using ugly URLs
Supports diagram caching as implemented in v3.1.0 of the asciidoctor-diagram
extension:
- Enables caching by default
- Sets default cache location to the compiled value of caches.misc.dir
Reduces duration of integration tests by:
- Generating GoAT diagrams instead of Ditaa diagrams
- Taking advantage of asciidoctor-diagram caching

This commit introduces a new option, backlinkHTML, to the Goldmark
footnote extension. This allows users to the set custom text for
footnote backlink anchors.
Closes#11434
This commit introduces a new option, enableAutoIDPrefix, to the Goldmark
footnote extension. When enabled, it prepends a unique prefix to
footnote IDs, preventing clashes when multiple documents are rendered
together. This prefix is unique to each logical path, which means that
the prefix is not unique across content dimensions such as language.
This change also refactors the extension's configuration from a boolean
to a struct.
Closes#8045
Add option ``aligny`` to specify the vertical alignment of the text
with respect to the ``y`` offset from the top of the image. Possible
values of ``aligny`` are ``top`` (default), ``center``, and ``bottom``.
The height of the block of text is measured from the top of the first
line to the baseline of the last line.
- ``top``: (Current behaviour) The top of the first line of the block of
text is at an offset of ``y`` from the top of the image.
- ``center``: The vertical center of the block of text is at an offset of
``y`` from the top of the image.
- ``bottom``: The baseline of the last line of the text is at an offset
of ``y`` from the top of the image.
Resolves#13414
* Make it work for all pages, including those created from content adapters and not backed by a file.
* Allow the `slug` to win, so the new tokens are:
`:contentbasename`:
1. ContentBaseName
`:slugorcontentbasename`:
1. Slug
2. ContentBaseName
Note that a page will always have a `ContentBaseName`, so no need to fall back to e.g. the title.
Closes#11722
Add an "alignx" option to the images.Text to control whether the value of the "x" option is the left border of the text (current behaviour), the center of each line or the right border.
