This implementation works with the 3DConnexion driver (sic!)
if PrusaSlicer.xml is stored into c:\Program Files\3Dconnexion\3DxWare\3DxWinCore64\Cfg\
The implementation is inspired with Blender, see code inside WITH_INPUT_NDOF blocks.
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.
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.
The wxString saga continues. wxWidgets 3.0 don't have the wxString::FromUTF8(const std::string&) overload, we must use the GUI::from_u8 helper
Also wxWidgets 3.0 don't allow to disable wxString->const char* conversion, so calling show_info(wxWindow*, wxString, const char*) was ambiguous
Several includes moved around
show just the label in the application title. For Win32, add the
" 32 bit" indicator, so that we may see clearly if somebody is running
a 32bit build on 64bit windows by a mistake.
which now will be used for preset choosers on sidebar a preset tabs.
+ for BitmapCache class added m_scale used for correct scaling of SVG images on Retina displays
+ some code clearing from unused functions or function's parameters
