MuPDF WASM Viewer Demo
I am letting people know of permissive alternatives (https://github.com/paulocoutinhox/pdfium-lib) and their usage in web components (PDFium.wasm + PDF.js).
My comment also serves as a promise to open-source my components under the same permissive license.
I don't want people exposed to unnecessary stress.

MuPDF WASM Viewer Demo
If webOS came out with WASM already in place, it would have been even better :)
When the Touchpad was firesaled, I got one and was disappointed with the PDF viewer. Because there was no such thing as WASM (or even asm.js) at the time, it used out of the box a service provided by Adobe that on request from the UI rendered tiles of the PDF at different resolutions, depending on the zoom level.
Since the frontend code was JS, it was easy to implement an alternative via mupdf (https://github.com/filmor/webos-pdf/blob/master/arxservice.c...). Via the same inefficient process (rendering png tiles onto the filesystem), the mupdf implementation was about 3 times faster than the original (though, it's been 13 years, the actual speedup might have been less :)).
