[chromium] Fat scrollbars on Windows in high-DPI mode.
Created attachment 186047 [details] Patch
Please wait for approval from abarth@webkit.org, dglazkov@chromium.org, fishd@chromium.org, jamesr@chromium.org or tkent@chromium.org before submitting, as this patch contains changes to the Chromium public API. See also https://trac.webkit.org/wiki/ChromiumWebKitAPI.
The Windows port of Chromium used GetSystemMetrics to determine the width of a scrollbar. This works fine if the device scale factor is 1, but results in double scaling of the scrollbar width in high-DPI mode since the system metrics call returns the width in pixels and not logical units.
Comment on attachment 186047 [details] Patch Ok. Is there a test for this issue on the Chromium side? I know we mock the Windows theme out in the WebKit-side tests.

Would you be willing to add one (either in WebKit or Chromium---whichever is easier for you)?
(In reply to comment #6) > Would you be willing to add one (either in WebKit or Chromium---whichever is easier for you)? Yes, I can look into adding a test. My preference is currently leaning to a Chromium-side layout test.
