45// When inserting a PDF file as an image or pasting PDF data from the clipboard, at least on a
46// Retina iMac, the resulting rendered image does not look sharp without this surprisingly large
47// extra scaling factor. Exact reasons unknown. And it isn't enough to have it be just 2 (which is
48// the actual Retina factor on my iMac). Possibly the fuzziness is related to what Pdfium uses to
49// render text.
50
51// Also, look at CountDPIScaleFactor() in vcl/source/window/window.cxx. The GetDPIScaleFactor() API
52// lies on macOS even more than it does on other platforms, it claims that the DPI scale factor is
53// always 1. But in fact most Macs nowadays have a HiDPI ("Retina") display. But we can't just "fix"
54// things by making GetDPIScaleFactor() always return 2 on macOS, even if that wouldn't be any more
55// wrong, because that then causes other regressions that I have no time to look into now.
