Alt-zoom (object view) focuses toward the bottom-left of the click when UI size isn't 100% (UI-scaled vs raw coordinates)

Description

When using the Object View camera mode, the target or point of focus is always very far off from where I've clicked, and in my experience so far it has always been to the bottom left from where I've clicked. So whenever I try to zoom in on a specific object, it never zooms in on what I want.

Steps to reproduce

We couldn't reproduce this on Linux: Alt-zoom centres on wherever you click. It may be Windows-specific (window/DPI scaling, mouse capture, or how modifier keys and clicks are reported). We're reviewing the Windows-specific paths and will ship a best-effort fix in a beta; please retest then and tell us if it's still off.

sky_line changed title from ~~[viewer] Alt-Zoom (Object View) not behaving as expected~~ to Alt-zoom (object view) focuses toward the bottom-left of the click when UI size isn't 100% (UI-scaled vs raw coordinates)

Reproduced. Cause found: it's the UI size setting, not Windows.

This reporter has UIScaleFactor = 1.225 (UI size about 122%). With any UI size other than 100%, Alt-zoom / object view focuses on a point toward the bottom-left of where you click, and the further you click from that corner, the bigger the miss. Somewhere in the Alt-zoom pick path, the click position is being used in UI-scaled coordinates (window pixels ÷ UI size) where raw window pixels are needed, which pulls every click toward the origin. The project owner reproduced it by changing UI size; at 100% it works correctly.

A fix is in progress: tracing the pick → ray → focus path, our Vulkan pick replacements included, for the scaled/raw mix-up. Normal click-selection and hover tips are being checked for the same problem.

Workaround until the fix ships: set UI size to 100% (Preferences > General > UI Size).
