the Chromebooks share their file system to Linux using the 9p file
system, which does not support setting file ownership. Newly PrusaSlicer
will detect platform and it will not panick if copy_file() cannot set
file ownership after copying. It just logs the incident, and on
chromebooks the loglevel for that incident is "Info", not "Error".
Adjusted the full screen mode to contain menu bar.
Moved Platform.cpp/hpp to libslic3r
Mark Ejection as failed if the wait() function fails. It seems that it is not simply possible
to retrieve the exit code of the process in that case (although it usually finishes sucessfully).
Some customers seem to posses a floppy drive (sic!) and some floppy
drives start spinning if accessed just to check whether there is
a medium plugged in or not.
From now, the A: and B: drives are not checked anymore for removable
media. Now let's pray nobody maps an SD card or flash drive to A: or B:

PrusaSlicer newly registers by Windows operating system for HID USB
plug / unplug notifications and for Volume attach / detach notifications,
and the background threads of the two respective services are waken up
on these Windows notifications.
The RemovableDriveManager also wakes up every 30 seconds to cope with
the drives ejected from Windows Explorer or from another application,
for example Cura, for which Windows OS does not send out notifications.
system call to the command line utility and send out the unmount
wxWidgets event immediately.
Hopefully improves 2.2.0-RC Eject is very slow in Linux (#3795)
This crash was caused by the RemovableDriveManager and 3DConnexion
detection services not being stopped correctly.
The fix executes all the tasks of the MainFrame at the language switch,
that are normally performed on application shut down.
1) On Windows and Linux, the device enumeration now runs at a background
thread, while it ran on the UI thread on idle, which may have been
blocking on some rare Windows setups, see GH #3515#3733#3746#3766
2) On OSX, the device enumeration now relies on OS callback, no
polling is required.
3) Refactored for cleaner interface.
