PDF Zoom for TA grading of scanned exam #12084
Description
Describe the bug
With our recent refactor of the PDF viewer within TA grading
(we removed the PDF annotator feature as it was unmaintained and a potential security vulnerability)
we have lost the ability to separately zoom the PDF document while TA grading a scanned exam.
Doing control/command/shift '+' to zoom the brower window causes both the PDF AND the rubric and all other aspects of the page. This is frustrating while grading a PDF that has small cramped handwriting.
For example, I might want to take a closer look at the ASCII art digram on this page:
But zooming in, the rubric also becomes comically large and I have to scroll way too much to select the marks that apply to this work:
Expected behavior
The user should be able to set and fix their desired level of zoom for the rubric (& other aspects of the Submitty web UI). Then they should be able to separately zoom in or zoom out of the each students pdf or png file to grade that work.
