This is now used as a crc field in the mapping rather than directly in mapping guids, for better mapping compatibility between versions of SDL.
Added SDL_GetJoystickGUIDInfo() to get device information encoded in a joystick GUID, so that mapping programs can clear the CRC from the GUID when generating mappings.
sort_controllers.py has been updated to extract the CRC from mappings created by older mapping programs and convert it into the new crc field. It will also take the CRC into account when checking for duplicate mappings.
Also regenerated the GUIDs for the PS2/PSP/Vita controller mappings, fixing https://github.com/libsdl-org/SDL/issues/6151
* Added support for mini-gamepad mode for Joy-Con controllers, matching the mapping for hid-nintendo on Linux and iOS 16
* Added the ability to merge left and right Joy-Con controllers into a single Pro-style controller
* Added the hint SDL_HINT_JOYSTICK_HIDAPI_SWITCH_COMBINE_JOY_CONS to control this merging functionality
* Removed the hint SDL_HINT_JOYSTICK_HIDAPI_JOY_CONS
Also added test functions for multi-line debug text display
Currently this only supports ASCII, as the font doesn't have the correct Latin-1 characters
Instead of using `trunc` to check the first ten digits, inexact test now
relies on an epsilon defining an acceptable range for the expected
result to be in.
Many tests were using the same underlying routine, as such three helper
functions were added:
- A wrapper to test double -> double functions.
- A wrapper to test (double, double) -> double functions,
- A wrapper for range tests on double -> double functions.
Split infinity and zero checks in their own functions.
The result of NAN tests is now logged.
The SDL_TestCaseReference structure were renamed to be more explicit.
Fixes bug with viewport not updating when moving window between monitors with different scale
factors on Windows (this should also fix the same issue on other OS'es, though untested)
- SDL_JoystickGUID -> SDL_GUID (though we retain a type alias)
- Operations for GUID <-> String ops are now in
src/SDL_guid.c and include/SDL_guid.h
- The corresponding Joystick operations delegate to SDL_guid.c
- Added test/testguid.c
I had assumed that only Linux users would be interested in GNOME-style
installed-tests, but in principle there's no reason why they can't be
used on non-Linux.

Added the ability to specify a name and the product VID/PID for a virtual controller
Also added a test case to testgamecontroller, if you pass --virtual as a parameter
This makes it more convenient to compile them alongside SDL, install
them in an optional package and use them as smoke-tests or diagnostic
tools. The default installation directory is taken from GNOME's
installed-tests, which seems as good a convention as any other:

As well as reducing duplication, this lets the tests load their resources
from the SDL_GetBasePath() on platforms that support it, which is useful
if the tests are compiled along with the rest of SDL and installed below
/usr as manual tests, similar to GNOME's installed-tests convention.

In Autotools, these are run by `make -C ${builddir}/test check`.
In CMake, they're run by `make -C ${builddir} test` or
`ninja -C ${builddir} test` or `ctest --test-dir ${builddir}`.

At the time I contributed this unit test, SDL had a relatively narrow
definition of what is a keyboard, approximately matching udev
ID_INPUT_KEYBOARD. Now it uses the equivalent of udev ID_INPUT_KEY,
which matches anything with keyboard keys, and not just reasonably
complete alphanumeric keyboards.

At the time I contributed this unit test, SDL didn't understand Linux
touchpads, but now it does.

Call SDL_RenderPresent after calling SDL_RenderReadPixels.
From "include/SDL_render.h":
"If you're using this on the main rendering target, it should be called after rendering and before SDL_RenderPresent()."
GLES2 always has them, and they work without hacks on Emscripten, unlike
client-side arrays.
I cleaned it up slightly, but this patch was mostly written by @bing2008.
Fixes#5258.
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.

* 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
