With pdf.js on Android, drawing can be glacially slow. In profiling, most time seems to be spent in fillText() and (if the PDF has images, at least) drawImage().
Some of this is solved by using SkiaGL (specificall, drawImage() is mostly better). Should be revisited.
Eugen, can you do some profiling of PDF.js on Android and see if these two are still prominent?
