zoom buttons / actions

[lfoppiano]

We should consider having some sort of zoom. Some ideas:

• magnifier on the cursor
• zoom buttons
• zoom activated by zoom-in/zoom-out (instead of scrolling) when the user's cursor is on the pdf area

is this feature under development?

it's a nice to have but at the moment I don't have time to implement it. Also actions are hard to develop due to the refresh-at-each-action approach of Streamlit.

Zoom buttons have been implemented in 0.0.26 (thanks to @danieljannai)
