PdfInkModule relies upon a client query to know the scale factor to apply when transforming points. This has included the zoom factor within the PDF viewer plugin, but has been missing any extra screen scaling for OS-level display scaling. HiRes on some macOS devices or Windows devices with display scale settings set to something other than 100% could cause a significant shift in stroke placement. Update the PdfViewWebPlugin::PdfInkModuleClientImpl to incorporate the device scale when providing zoom for Ink strokes.

Chromium
Chromium is an open-source browser project that aims to build a safer, faster, and more stable way for all users to experience the web.
The project's web site is https://www.chromium.org.
To check out the source code locally, don't use git clone
! Instead,
follow the instructions on how to get the code.
Documentation in the source is rooted in docs/README.md.
Learn how to Get Around the Chromium Source Code Directory Structure.
For historical reasons, there are some small top level directories. Now the guidance is that new top level directories are for product (e.g. Chrome, Android WebView, Ash). Even if these products have multiple executables, the code should be in subdirectories of the product.
