SDL considers a hidden window to be unmapped and blocks or defers certain operations until the window is shown again, however, the X11 and Cocoa backends would set the hidden flag when the window was minimized, which blocked the functionality of SDL_RestoreWindow().
Specify that a window with the hidden flag set is unmapped and not visible on the desktop or in the dock/taskbar without a call to SDL_ShowWindow(), and don't set the hidden flag in the X11 and Cocoa backends when the window is in the minimized state, but still mapped to the desktop.
CMake's SDL_build_config.h force disables HAVE_STDIO_H when buiding
winrt in non-libc mode.
Becase CreateFileEx is not available in UWP mode, use CreateFile2
instead.
This usually manifests as a clicking sound, because it often produces
a value outside the range -1.0f to 1.0f based on whatever random data
is past the buffer, which later stages of audio conversion will clamp
to a maximum value for the audio format. Since this tends to be a single
bad sample generated at the end of the resampled buffer, it sounds like
a repeating click in streamed data.
I'd like a more efficient means to clamp this value to not overflow the
buffer, but this puts out the immediate fire.
This happens in the KMSDRM driver, once after video init, setting a blank default cursor, and once when creating a window when the KMSDRM mouse is initialized.
Also fixed a memory leak freeing the default cursor at shutdown
testcontroller expects to be able to call SDL_GetGamepadStringForButton() and find that name in the binding string
We can revisit this later if it becomes important to use new names in bindings. @smcv
The sequence order of the four paddles is not obvious, with SDL and Xbox
controllers swapping the order of P2 and P3 relative to each other.
If we group them into left and right, then it becomes more obvious.

The current status is stored in the SDL_rwops 'status' field to be able to determine whether a 0 return value is caused by end of file, an error, or a non-blocking source not being ready.
The functions to read sized datatypes now return SDL_bool so you can detect read errors.

I don't know of any specific issue with this, but third party PS4 controllers have had issues with reports that are specific to Sony hardware, so this is a speculative change to prevent issues with future controllers.
If it turns out that these reports are valid and useful for third party controllers, we can back this change out.
We should always report touchpad and battery status if they are available. We just want to make sure we don't enable enhanced reports unless the application wants that behavior.
Add SDL_ShowWindowSystemMenu() to display the system-level menu for windows. Typically, this is done by right-clicking on the system provided window decorations, however, if an application is rendering its own client-side decorations, there is currently no way to display it. This menu is provided by the system and can provide privileged desktop functionality such as moving or pinning a window to a specific workspace or display, setting the always-on-top property, or taking screenshots. In many cases, there are no APIs which allow applications to perform these actions manually.
Implemented for Wayland via functionality provided by the xdg_toplevel protocol, Win32 via the undocumented message 0x313 (typically called WM_POPUPSYSTEMMENU), and X11 via the "_GTK_SHOW_WINDOW_MENU" atom (supported in GNOME and KDE).
This rips up the entire SDL audio subsystem! While we still feed the audio device from a separate thread, the audio callback into the app is now gone a totally optional alternative.
Now the app will bind an SDL_AudioStream to a given device and feed data to it. As many streams as one likes can be bound to a device; SDL will mix them all into a single buffer and feed the device from there.
So not only does this function as a basic mixer, it also means that multiple device opens are handled seamlessly (so if you want to open the device for your game, but you also link to a library that provides VoIP and it wants to open the device separately, you don't have to worry about stepping on each other, or that the OS will fail to allow multiple opens of the same device, etc).

It's not intuitive from a developer's point of view that you wouldn't get these events. If they're impacting performance they can be explicitly disabled for applications that don't want them.
When a hardware keyboard is attached, it can take over 100 ms for the keyboard event to generate text input. In that case we want to record that we recently received a keyboard event so we don't synthesize duplicate virtual key press/release events for the input text.
This is another attempt to make sure we don't cause beeps from unhandled key presses while still allowing full text input functionalty.
If this isn't selective enough, we might need to go up the responder chain to see what's going to handle the event before passing it along.
