Sam Lantinga 66058bbbd5 Fixed exception accessing Bluetooth devices on Android 12
Since accessing Bluetooth prompts the user for permission on both Android and iOS, and we only need it for Steam Controller support, we'll leave it off by default. You can enable it by setting the hint SDL_HINT_JOYSTICK_HIDAPI_STEAM to "1" before calling SDL_Init()

Misa 3bf7994fe2 Add and use SDL_FALLTHROUGH for fallthroughs
Case fallthrough warnings can be suppressed using the __fallthrough__
compiler attribute. Unfortunately, not all compilers have this
attribute, or even have __has_attribute to check if they have the
__fallthrough__ attribute. [[fallthrough]] is also available in C++17
and the next C2x, but not everyone uses C++17 or C2x.

So define the SDL_FALLTHROUGH macro to deal with those problems - if we
are using C++17 or C2x, it expands to [[fallthrough]]; else if the
compiler has __has_attribute and has the __fallthrough__ attribute, then
it expands to __attribute__((__fallthrough__)); else it expands to an
empty statement, with a /* fallthrough */ comment (it's a do {} while
(0) statement, because users of this macro need to use a semicolon,
because [[fallthrough]] and __attribute__((__fallthrough__)) require a
semicolon).

Clang before Clang 10 and GCC before GCC 7 have problems with using
__attribute__ as a sole statement and warn about a "declaration not
declaring anything", so fall back to using the /* fallthrough */ comment
if we are using those older compiler versions.

Applications using SDL are also free to use this macro (because it is
defined in begin_code.h).

All existing /* fallthrough */ comments have been replaced with this
macro. Some of them were unnecessary because they were the last case in
a switch; using SDL_FALLTHROUGH in those cases would result in a compile
error on compilers that support __fallthrough__, for having a
__attribute__((__fallthrough__)) statement that didn't immediately
precede a case label.

testwm2: Fix video modes menu hit detection when highdpi or logical size used (#4936)
* SDLTest_CommonDrawWindowInfo: log SDL_RenderGetScale, SDL_RenderGetLogicalSize

* testwm2: fix video modes menu hit detection in High DPI cases

- also when logical size is specified, e.g.
  `--logical 640x480 --resizable --allow-highdpi`

* add function to determine logical coordinates of renderer point when given window point

* change since to the targeted milestone

* fix typo

* rename for consistency

* Change logical coordinate type to float, since we can render with floating point precision.

* add function to convert logical to window coordinates

* testwm2: use new SDL_RenderWindowToLogical

* SDL_render.c: alternate SDL_RenderWindowToLogical/SDL_RenderLogicalToWindow

Sam Lantinga fd79607eb0 Added SDL_GetWindowMouseRect()

Ethan Lee 4b42c05ba1 video: Add SDL_SetWindowMouseRect.
This API and implementation comes from the Unreal Engine branch of SDL, which
originally called this "SDL_ConfineCursor".

Some minor cleanup and changes for consistency with the rest of SDL_video, but
there are two major changes:

1. The coordinate system has been changed so that `rect` is _window_ relative
   and not _screen_ relative, making it easier to implement without having
   global access to the display.
2. The UE version unset all rects when passing `NULL` as a parameter for
   `window`, this has been removed as it was an unused feature anyhow.

Currently this is only implemented for X, but can be supported on Wayland and
Windows at minimum too.

__has_include() was added in VS 2017 15.3, so this works out to essentially
the same _MSC_VER >= 1911 check we had before for MSVC but works for non-MSVC
compilers also.

Cameron Gutman d8b53e821e direct3d11: fix SDK version requirement for non-CMake build
The D3D11 renderer requires Direct3D 11.1 (d3d11_1.h), not Direct3D 11.0
(d3d11.h). In terms of SDKs, that's the Windows 8 SDK or later.

We should probably rename HAVE_D3D11_H...

Export SDL_LinuxSetThreadPriorityAndPolicy() function (#4877)
It's marked as being a public symbol internally, however, it was missing from the header files and not visible in the shared library.  This adds it to the necessary headers and to the DynAPI list to expose it for use by applications.
