Our current version is getting rather outdated. Replace by
the *legacy* bundle: pdfjs now provides a non-polyfilled version of
the library, which is probably faster though it doesn't save overly
much (for the entire bundle anyway). Use polyfilled version for
safety, though it's unclear whether non-chromium Edge is still
supported by Odoo. If not, we could just use the non-polyfilled
version.
The difference is quite large for pdf.js (+32.5%), however it is much
less consequential for the sandbox (+1%) or for the much larger
worker (+5.6%). The biggest difference is likely performances
but... who knows?
Notes:
- The main reason for this change is that automated vulnerability
scanner have apparently started scanning for `postMessage(..., '*')`
and the previous bundles includes a version of corejs polyfills
without zloirock/core-js#542), therefore triggering those scans. As
the PR notes this is almost certainly not a concern because of the
innocuous payload, but there is no reason to waste time on those
reports if we don't *have* to.
- The bundle now includes "standard fonts", those were removed as
they're heavy and may not be necessary for our usage (?).
- All the bitmap images were dropped and replaced by svgs, which is
nice.
- The local changes since the previous update were *not* impacted in
this, the entire thing was just reset to upstream. This means
changes which were backported (922c7c72, 6943714f) are superseded
but more odoo-specific changes will have to be reapplied in further
commits.
