Review Comment:
In the default configuration, it's a small thumbnail rectangle as seen in
the screenshot in the PR, not a full-size copy of the component.
But looking at DragAndDropFeedbackVisualizer, which instantiates the
DragWindow, there is a WinSysPrefs.DND_SMALLWINDOWS option that can be turned
off to get the full-size window. If a platform app happens to be overriding
that setting, it's true that the buffer could be several megabytes.
Should I make some efforts to skip the scaling in the
WinSysPrefs.DND_SMALLWINDOWS=false case?
