This reverts commit e20fbb00d0e0219b710da24664e81a10b12c703a. Reason for revert: Breaks WebRTC roll to Chromium, see: https://chromium-review.googlesource.com/c/chromium/src/+/6218060 Example of error: https://ci.chromium.org/ui/p/chrome/builders/ci/win-arm64-rel-ready/51821/test-results?sortby=&groupby= Original change's description: > Get DeviceScaleFactor for the captured monitor/screen > > Accesses DeviceScaleFactor using the windows API > GetScaleFactorForMonitor and adds it to the DesktopFrame. In a follow-up > CL, this value is propagated to > DesktopCaptureDevice::Core::OnCaptureResult where it is added to the > frame metadata. > > In a follow-up CL, add RegisterScaleChangeEvent to get notified whenever > the device scale factor changes. > > Design doc: go/expose-captured-surface-resolution > > Bug: chromium:383946052 > Change-Id: I363af33c569419d95ddf31a0cc2f9cecf6fb0c7b > Reviewed-on: https://webrtc-review.googlesource.com/c/src/+/374344 > Reviewed-by: Henrik Andreassson <henrika@webrtc.org> > Reviewed-by: Mark Foltz <mfoltz@chromium.org> > Commit-Queue: Palak Agarwal <agpalak@google.com> > Reviewed-by: Ilya Nikolaevskiy <ilnik@webrtc.org> > Cr-Commit-Position: refs/heads/main@{#43827} Bug: chromium:383946052 Change-Id: I3065b278939ca0e686ee6da0f0721082bc0c99e8 No-Presubmit: true No-Tree-Checks: true No-Try: true Reviewed-on: https://webrtc-review.googlesource.com/c/src/+/375902 Owners-Override: Mirko Bonadei <mbonadei@webrtc.org> Bot-Commit: rubber-stamper@appspot.gserviceaccount.com <rubber-stamper@appspot.gserviceaccount.com> Commit-Queue: Mirko Bonadei <mbonadei@webrtc.org> Cr-Commit-Position: refs/heads/main@{#43829}
