* Make Win32 fullscreen and borderless windows minimizable

* reduced a few ifdefs, fixed an unused warning if built w/o SDL_HAVE_YUV.

* rawinput: Fix double detection of gamepads on some 3rd party X360 wireless receivers

The name that the Raw Input joystick driver pulls from the HID stack comes
from USB string descriptors contained on the device. For official wireless
receivers, this always contains "Xbox 360 Wireless Receiver for Windows"
which matches the friendly name that WGI provides.

3rd party Xbox 360 wireless receivers may have different strings in their
USB string descriptors (one uses "XBOX 360 For Windows" instead). This
fails to match WGI's name and causes Raw Input and WGI to both report the
same gamepad.

Since wireless Xbox 360 controllers seem to have a consistent VID/PID
regardless of the adapter enumerating them, we can also match on that to
catch these.

The duplicate case reported to me was:
Controller (XBOX 360 For Windows) - 030000005e040000a102000000007200
Xbox 360 Wireless Receiver for Windows - 030000005e0400000000000000007701

* Fix relative mouse input for Unvanquished (unvanquished.net)

Here's an IRC dump that hopefully explains the issue this fixes:

> I'm debugging something odd where, for a libre game,
  unvanquished.net (a FPS), relative mouse input in fullscreen is
  buggy
> it's like, working mostly ok, but it has a weird
  performance/cleanup bug
> after some time in relative mouse input mode, some time as low
  as 15s, usually more, the SDL sends A LOT of relative mouse
  input per frame
> almost all of which have xrel==0 && yrel==0
> by A LOT, I mean that after ~1min, it's usually in the
  thousands per frame
> each frame, a while ( SDL_PollEvent( &e)) loop reads the
  inputs, but it seems SDL is not clearing the list.
> one way to clear the list is to open the in-game console or
  menu, which switches the input mode to absolute, then close it
  which gets a working relative input mode (for some time at least)
> I've shown the issue to be present with SDL2.0.20 but not with
  2.0.14 on my system
> some other players on Arch Linux (SDL2.0.20) report a possibly
  related issue, where some keys seem to be pressed at random
> I've did some bisection on SDL master, and I've found that
  there are actually two commits involved, one breaking it
  totally (no input at all), and one fixing it partially (with
  the problem described above)

First related commit that breaks it totally:

	commit 82793ac
	Author: Sam Lantinga <slouken@libsdl.org>
	Date:   Thu Oct 14 14:26:21 2021 -0700

	    Fixed mouse warping while in relative mode

	    We should get a mouse event with an absolute position and no relative motion and shouldn't change the OS cursor position at all

Second related commit, that halfway fixes it:

	commit 31f8c3e
	Author: Sam Lantinga <slouken@libsdl.org>
	Date:   Thu Jan 6 11:27:44 2022 -0800

	    Fixed event pump starvation if the application frequently pushes its own events

Reverting the first commit did fix the issue for me, but would
probably reintroduce the bug it was fixing(?). This patch should
fix it for everyone hopefully.

DaemonEngine/Daemon#600 is the upstream
bug, and contains some early investigation.

* SDL_render.c: remove unsused case, since renderer target has been forced to NULL previously (see bug libsdl-org#4213)

* Add mapping for Logitech Precision Gamepad

* Also fix Android crash when SDL_HIDAPI_DISABLED set to 1

The Java code needs the native functions to be implemented, even if
they're not surfaced via the C API, therefore, a stub version of

SDL_HIDAPI_DISABLED set to 1.

* use != '\0' comparison instead of SDL_strlen in the functions of SDL_getenv

* make SDL_strcasecmp standard compliant

* optimize the SDL_str(case)cmp functions

* Avoid trying to use texture framebuffers on emscripten

* Fixed freeing a constant string (thanks @gnrlwart)

* Android: add SetWindowResizable() implementation

This is only provided when the window is not SDL_WINDOW_FULLSCREEN (see SDL_video.c).
Final orientation also depends on SDL_HINT_ORIENTATIONS.

Using wl-output to get the desktop display dimensions and dividing by the integer scale factor will not return the correct result when using a desktop with fractional scaling (e.g. a 3840x2160 display at 150% will incorrectly report the scaled desktop area as 1920x1080 instead of 2560x1440).  Use the xdg-output protocol, if available, to retrieve the correct desktop dimensions and offset.

Versions 1 through 3 of the protocol are supported.

* Vita: support audio format fallback

* x11: Minor cleanups and corrections in X11_ShowMessageBox.

Reference issue libsdl-org#3254.

* Avoid depending on libwayland 1.20 unnecessarily

When using shared linking (linking in the normal way with
-lwayland-client) rather than loading Wayland libraries dynamically at
runtime, listing symbols that don't exist in the current version results
in a build failure. We don't actually call wl_proxy_marshal_flags() or
wl_proxy_marshal_array_flags() directly; the reason we need them is
that they're called by the code generated by wayland-scanner >= 1.20.

If we're building against an older Wayland library, then we'll have its
corresponding version of wayland-scanner (mismatched versions are not
supported), so we won't need those two symbols, and can avoid generating
a dependency on them.

Conversely, if we're building against a newer Wayland library, the
generated code will call them unconditionally, so we cannot treat them as
optional and gracefully fall back: that would result in a crash. Instead,
treat them as a mandatory part of the Wayland library, so that if they
are not found at runtime, we can fall back to X11 without crashing.

libwayland 1.18 is in several LTS distributions (Ubuntu 20.04,
Debian 11, RHEL 8) so avoiding a hard dependency on 1.20 is quite
useful.

* video: wayland: Use wp-viewporter for fullscreen with non-native resolutions

Wayland doesn't support mode switching, however Wayland compositors can support the wp_viewporter protocol, which allows for the mapping of arbitrarily sized buffer regions to output surfaces.  Use this functionality, when available, for fullscreen output when using non-native display modes and/or when dealing with scaled desktops, which can incur significant overdraw without this extension.

This also allows for the exposure of arbitrarily sized, emulated display modes, which can be useful for legacy compatability.

* wayland: Minor fix for old compilers

* video: wayland: Expose more resolutions for mode emulation

Expose as many emulated display modes as possible.  They will currently display stretched to the display's native desktop aspect, but if an application requires a hardcoded resolution, it will work at minimum.

Aside from the change in the emulated display mode list, the Wayland event handling code had to be updated to support separate scaling for the x and y axes, as square pixels are no longer guaranteed.

* video: wayland: Use viewports for non-fullscreen windows with fractional scaling

Use viewports for non-fullscreen windows when the desktop uses fractional scaling and the window is flagged as DPI-aware to provide a backbuffer mapped as close to 1:1 output as possible.  In the cases of odd window sizes the backbuffer may be a pixel off of scaling perfectly into the window size due to its scaled size being rounded off, but a minute amount of scaling during output is likely preferable to the large amounts of overdraw needed with integer scaled buffers.

* Vita: add audio capture support

* Vita: add SDL_GetPreferredLocales support

* stdinc: SDL_COMPILE_TIME_ASSERT defines shouldn't have a semicolon.

* x11: Catch X11 errors in X11_SetWindowPosition and X11_SetWindowSize.

The functions can go south if other operations are in progress, like
X11_SetWindowBordered, which might be doing something traumatic behind the
scenes of the window manager.

We can't make these tasks totally synchronous, which would fix the problem,
because not only can the window manager block however long it wants, it might
also decide to deny our requests without any notification, so we'd be waiting
forever for a window change that isn't coming.  :(

Fixes libsdl-org#5274.

* joystick: Fix rumble issues on PS5 HIDAPI controllers

We were returning the report size from HIDAPI_DriverPS5_RumbleJoystick() rather
than 0 upon success, causing SDL_JoystickRumble() (and callers) to think that
rumbling failed.

This didn't cause major problems until 1868c5b, when it started preventing
rumble state from being persisted in the joystick core, even though it was
successfully sent to the hardware.

This led to all sorts of strangeness, including broken rumble duration and
attempts to stop rumble being discarded.

* Ignore focus change messages that contradict GetForegroundWindow.

On Wine, when a window is programmatically minimized in response
to losing focus, we receive a WM_ACTIVATE for the deactivation,

This is probably a Wine bug, but it may take a while to fix and

Partially fixes the mouse cursor in UE5 editor.

We really need to make global mouse support a feature query...

* wayland: Try to detach at the beginning of ShowWindow, just in case.

* wayland: Add support for TOOLTIP/POPUP_MENU

* video: Don't minimize fullscreen windows on focus loss by default when mode switching is disabled

When mode switching is disabled in a video backend, fullscreen windows are basically just fullscreen desktop windows with different internal scaling.  As no mode switching occurs, there's no need to minimize them on focus loss by default.  This can still be overridden by explicitly setting the internal hint for minimizing on focus loss.

This has the side effect of fixing a bug on GNOME, where, when a fullscreen Wayland window has it's focus lost and restored via alt+tab followed by switching back to windowed mode, the top portion of the window won't end up being obstructed by GNOME's top bar.

* Added controller mapping for the Thrustmaster Dual Analog 3.2 on Linux

* Enable evdev-based gamecontrollerdb on FreeBSD

* simplify SDL_GetBasePath on windows
- use GetModuleFileName directly (as recommended)

* use explicit GetModuleFileNameW

* Remove HWND_TOPMOST for fullscreen windows

Fixes libsdl-org#5509

* SDL_render.c: internally change viewport/cliprect type from SDL_FRect to SDL_DRect (double precision). (see bug libsdl-org#5547)

* Don't call scandir() inside of scandir()

This works around a crash in address sanitizer

* Fixed compile warnings

* x11: Revert "Fix keymap updating for X11 backend"

This reverts commit de6d290.

This patch had multiple issues, discussed in libsdl-org#5520.

* Fixed build

* Fix recent changes in VitaSDK

* SceKernelMemBlockType to unsigned int

* Fix a -Wshadow warning

* Remove an unused function prototype

* WhatsNew.txt: Add SDL_FRectEqualsEpsilon()

* Add SDL_FLT_EPSILON.

* SDL_Rect: Use a default epsilon in SDL_FRectEquals()

Add SDL_FRectEqualsEpsilon() for when more control over
equality test is required.

* test: Basic tests for SDL_FRectEquals

Based on the integer version. These tests mostly check that input
isn't mangled and that invalid input gives the expected negative
result.

* hidapi: Wrap CopyHIDDeviceInfo in define checks.

The purpose of this is to silence a 'defined but not used'
warning.

* os2: SDL_DestroyMutex should ignore NULL mutexes.

Every other backend does this, so this should match, now.
It's possible this was harmless, but we can avoid the system call
and the (likely?) debug message when it fails, though!

* windows: Fix calling convention for RoInitialize/RoUninitialize

Fixes libsdl-org#5563

* windows: Fix RoInitialize() failure after a CoInitializeEx() call using apartment threading

This mirrors the same codepath in WIN_CoInitialize() which handles STA and MTA.

* WGI: Keep a reference to the MTA to avoid crashing on COM teardown

Fixes libsdl-org#5552
Fixes libsdl-org#5270

* WGI: Only call RoUninitialize() if RoInitialize() succeeded

* Handle potential out of memory condition when working with hints

* SDL_Rect: Add \sa documentation block to SDL_FRect

* Return a correlation error when trigger rumble is attempted without correlation

* Fixed build

* SDL: sometimes the PS5 controller doesn't report having to power even when connected over USB. Possibly related to being completely charged? Either way we already know that it's USB or BT so let's use the driver's knowledge instead.

* Added support for the Backbone One controller on iOS

* Revert "Fix relative mouse input for Unvanquished (unvanquished.net)"

This reverts commit 3318590.

Fixes libsdl-org#5569

* hidapi, libusb: import mainstream commit 536bad201e

* Fixed logical size synchronization issue on macOS

https://discourse.libsdl.org/t/sdl-2-0-22-prerelease/35306/6

* x11: revert checks for _NET_WM_STATE_FULLSCREEN changes.

This reverts commit 8597735.
This reverts commit 0249df9.

Fixes libsdl-org#5572.
Reopens libsdl-org#5390.
