Also cleaned up logic for whether we need to poll for events:
- We need to periodically poll for joysticks to handle hotplug.
- We need to frequently poll for joysticks and sensors when they're open so their state can be updated
This function is useful for accumulating relative mouse motion if you want to only handle whole pixel movement.
e.g.
static float dx_frac, dy_frac;
float dx, dy;
/* Accumulate new motion with previous sub-pixel motion */
dx = event.motion.xrel + dx_frac;
dy = event.motion.yrel + dy_frac;
/* Split the integral and fractional motion, dx and dy will contain whole pixel deltas */
dx_frac = SDL_modff(dx, &dx);
dy_frac = SDL_modff(dy, &dy);
if (dx != 0.0f || dy != 0.0f) {
...
}
Instead of indexing into an internal list of devices which requires locking, we return a list of device IDs which can then be queried individually.

If you care about timestamps you'll also want to catch all of the sensor events instead of just polling the current state. For example, Nintendo Switch controllers generate 3 sensor events with distinct values for each polling interval.
* Remove depth field from SDL_CreateRGBSurfaceWithFormat and SDL_CreateRGBSurfaceWithFormatFrom
* Removed unused 'flags' parameter from SDL_CreateRGBSurface and SDL_CreateRGBSurfaceWithFormat
* Removed unused 'flags' parameter from SDL_ConvertSurface and SDL_ConvertSurfaceFormat
I ran this script in the include directory:
```sh
sed -i '' -e 's,#include "\(SDL.*\)",#include <SDL3/\1>,' *.h
```
I ran this script in the src directory:
```sh
for i in ../include/SDL3/SDL*.h
do hdr=$(basename $i)
if [ x"$(echo $hdr | egrep 'SDL_main|SDL_name|SDL_test|SDL_syswm|SDL_opengl|SDL_egl|SDL_vulkan')" != x ]; then
find . -type f -exec sed -i '' -e 's,#include "\('$hdr'\)",#include <SDL3/\1>,' {} \;
else
find . -type f -exec sed -i '' -e '/#include "'$hdr'"/d' {} \;
fi
done
```
Fixes https://github.com/libsdl-org/SDL/issues/6575
* The header is no longer dependent on SDL build configuration
* The structures are versioned separately from the rest of SDL
* SDL_GetWindowWMInfo() now returns a standard result code and is passed the version expected by the application
* Updated WhatsNew.txt and docs/README-migration.md with the first API changes in SDL 3.0
Disabling RAWINPUT on Windows 10 causes these issues:
* All Xbox controllers are named "XInput Controller".
* Trigger rumble no longer works.
* "XInput Controllers" are now also listed as separate haptic devices
It's only needed to support more than 4 Xbox controllers, and adds significant complexity to the joystick processing, and we regularly get bugs from people who aren't using an SDL window who need to turn on SDL_HINT_JOYSTICK_THREAD.
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
