Subject Re: Hardware Acceleration

Some more ideas:
- I have about 30 files that are slow or were slow (but many still are), 
if you like to investigate for "opportunities"
- the one I mentioned yesterday renders in better speed with PDF.js. 
I've never heard that they use the GPU, usually they are faster than us
- video about PDF rendering in general by the PDF-Tools boss: 
https://www.youtube.com/watch?v=TiqDqd-1pwU&t   (very scary!)
- video about PDFBox https://www.youtube.com/watch?v=Sf8BfGaRUkk    and 
- you're not the first person who would write a thesis related to 
PDFBox, this guy wrote about text extraction:
