We get a lot of user questions about where things are
on macOS.

Also, describe high DPI scaling after the other user
interface options.

+    \list

+            the scaling factor and use it for \QC.
+        \li On Linux, \QC leaves it to the user to enable high DPI scaling,
+            because the process varies so much on different distributions
+            and windowing systems that it cannot be reliably done automatically.
