This is currently supported on Linux and macOS. iOS and Android are not
supported at all, Windows support could be added with some changes to the libusb
backend. The Visual Studio and Xcode projects do not use this feature.
Based on Valve Software's hid.cpp, written in collaboration with Andrew Eikum.

As I have seen, SDL implements its own command line parser for Windows in SDL_windows_main.c. Unfortunately, it doesn't seem to allow command line arguments with trailing backslashes if quoting is required.
Usually, when you write an application that gets command line arguments passed as argc and argv, the parsing is done by parse_cmdline. The Windows API also provides the function CommandLineToArgvW, so an application can parse itself if only the command line string is provided. Both functions behave almost identically according to their documentation. If the argument "\\" (including the quotes) is passed, they both turn it into a single backslash.
The SDL command line parser on the other hand doesn't recognize the second quote character as the closing character in this example and therefore includes it in the parsed argument. The parser does not count the number of backslashes preceding a quote. It always treats a quote as escaped if a backslash is in front of it. Therefore, it should be impossible to quote and escape an argument correctly, if it has a trailing backslash and contains characters that require quoting.
Of course, each application is allowed to implement its own parsing rules, so SDL is free to do so. But the problem I see is that there are arguments, that are impossible to be passed to the parser correctly, as I described above. Is there a reason, why SDL does not simply use CommandLineToArgvW instead of implementing its own parser?
Here are some links that show that correct argument parsing, as it is usually done in Windows, is quite complicated:

Unlike iOS and macOS, tvOS does not have any persistent local storage. In fact, the ApplicationSupport directory pointed to by the existing Cocoa GetPrefPath() throws an error whenever any attempt is made to access it. To get any local storage on an Apple TV, our only option is to use a temporary cache directory.
This patch changes the tvOS PrefPath to this cache directory and also logs a critical warning that this if developers want their save data to persist across game sessions, they must use some form of iCloud storage.

I notice that, somehow, when locking the mouse into place(using SDL_SetRelativeMouseMode), somehow at least the movement information gets through to both mouse movement and touch movement events?
My app handles both, so when moving a touched finger accross the app(using RDP from an Android device) I see the mouse moving inside the app when it shouldn't(meaning that the touch movement is ignored properly by the app(press-location dependant) but the mouse movement is still performed due to the mouse movement events)?

I have a knock off wired xbox 360 controller called afterglow for xbox 360 controller. Despite there being a few afterglow controllers in the controller mapping the guid of my controller seems to map to Generic Xbox pad. This binding is as follows:
```
"030000006f0e00001304000000010000,Generic X-Box pad,a:b0,b:b1,back:b6,dpdown:h0.4,dpleft:h0.8,dpright:h0.2,dpup:h0.1,guide:b8,leftshoulder:b4,leftstick:a0,lefttrigger:a2,leftx:a0,lefty:a1,rightshoulder:b5,rightstick:a3,righttrigger:a5,rightx:a3,righty:a4,start:b7,x:b2,y:b3,",
```
When running openmw I have a strange issue that the joysticks work for up and down movements but not for side to side. I managed to track this down to the side to side events being classified as joystick events instead of gamepad events.
I believe this is due to both "leftstick" and "leftx" being bound to "a0" which seems odd to me. If I change openmw's mappings to remove these the controller works as expected. I was hoping someone who knows a lot more than me (as I have only been exploring this today trying to fix my controller) would know what is happening
With multitouch, register to receive XI_Motion (which desctivates MotionNotify),
so that we can distinguish real mouse motions from synthetic one.
