+++ This bug was initially created as a clone of Bug #1214766 +++ Changes since last update: #6528 Ensure that `Dict_getArray` doesn't fail if `xref` in undefined (PR 6485 follow-up) #6531 Fixes bluebeam password protection issue #6532 Add unit-tests for PR 6531 #6540 Add unit-tests for the `onPassword/onProgress` callbacks of the API #6550 Ignore operators that are known to be unsupported #6543 Prevent getOperatorList from failing to correctly parse OPS.paintXObject for TilingPatterns that are missing some /Resources entries (issue 6541) #6554 Add a reduced test-case for issue 4575 #6557 Pushing update reason for gh-pages and bower. #6546 [api-minor] Adds controlled destruction of the worker. Landing this with rs=bdahl per an offline discussion we had about trying to update with greater frequency to make bisection easier in the future.

PdfStreamConverter.jsm changes still need review from Mossop, though.

#6546 is here to help with bug 1016737 -- we need to update tests to wait until PDFViewerApplication.close promise is resolved.
