If someone needs to, say, include an SDL_Storage object, they can simply point userdata at a structure that includes the the storage and any other data needed in enumeration.
Add the xdg-foreign-unstable-v2 protocol and use it to create export handles for toplevel windows, which will be used when an external component, such as the file chooser portal, requires it.
When initializing SDL with the flag SDL_INIT_AUDIO or SDL_INIT_SENSOR the event subsystem also gets initialized(SDL_INIT_EVENTS). This isn't mentioned in the comments.
This commit adds these two comments.
- SDL_RWops is now an opaque struct.
- SDL_AllocRW is gone. If an app is creating a custom RWops, they pass the
function pointers to SDL_CreateRW(), which are stored internally.
- SDL_RWclose is gone, there is only SDL_DestroyRW(), which calls the
implementation's `->close` method before freeing other things.
- There is only one path to create and use RWops now, so we don't have to
worry about whether `->close` will call SDL_DestroyRW, or if this will
risk any Properties not being released, etc.
- SDL_RWFrom* still works as expected, for getting a RWops without having
to supply your own implementation. Objects from these functions are also
destroyed with SDL_DestroyRW.
- Lots of other cleanup and SDL3ization of the library code.
Use memfd_create() to allocate the temporary SHM backing file in memory, and set the size with posix_fallocate(), which will return an error on insufficient space vs ftruncate(), which will silently succeed and allow a SIGBUS error to occur if the unbacked memory is accessed.
Additionally, make the legacy path more robust by unlinking the temp file, so it won't persist after close, and unmapping the shared memory buffer.
This adds HIDAPI support for DualShock 3 controllers on Windows, addressing the current absence of this feature in SDL. To utilize this functionality, the official Sony driver 'sixaxis.sys' must be installed. HID offers several advantages over DirectInput, including rumble support and the ability to control the LED lights that display the controller number.
This reverts commit b9ab3269823ea329757aada3a20ef97abf1a9f6d.
@rainerdeyke pointed out:
"This commit is incorrect. Flipping both horizontally and vertically is not equivalent to flipping diagonally."
Since SDL_RenderFlip is an enum, SDL_FLIP_HORIZONTAL and SDL_FLIP_VERTICAL can not be OR'ed to get the "SDL_FLIP_DIAGONAL".
Render code is actually able to perform these 3 kind of "flipping" so I just added a new enum called SDL_FLIP_DIAGONAL with the OR'ed value (3) so it can be used.
