These are integer values internally, but the API has been changed to make it easier to mix other render code with querying those values.
Fixes https://github.com/libsdl-org/SDL/issues/7519
This declares that any `const char *` returned from SDL is owned by SDL, and
promises to be valid _at least_ until the next time the event queue runs, or
SDL_Quit() is called, even if the thing that owns the string gets destroyed
or changed before then.
This is noted in the headers as "the SDL_GetStringRule", so this will both be
greppable to find a detailed explaination in docs/README-strings.md and
wikiheaders will automatically turn it into a link we can point at the
appropriate documentation.
Fixes#9902.
(and several FIXMEs, both known and yet-undocumented.)
Added SDL_Vulkan_DestroySurface, its documentation and corresponding platform specific implementations. Fixed some header inclusion orders to improve consistency between platforms. Added TODOs regarding MetalView creation and destruction which will benefit from the new functionality.
The flags parameter has been removed from SDL_CreateRenderer() and SDL_RENDERER_PRESENTVSYNC has been replaced with SDL_PROP_RENDERER_CREATE_PRESENT_VSYNC_NUMBER during window creation and SDL_PROP_RENDERER_VSYNC_NUMBER after renderer creation.
SDL_SetRenderVSync() now takes additional values besides 0 and 1.
The maximum texture size has been removed from SDL_RendererInfo, replaced with SDL_PROP_RENDERER_MAX_TEXTURE_SIZE_NUMBER.
The shorthand version of this function didn't allow specifying a controller name, which seems pretty important. It seems like anyone actually implementing a virtual joystick is going to want to use some of the extended functionality.
This allows applications to re-query the values if the system locale is changed during runtime, and better matches the other locale functions. A note is included in the documentation mentioning that this can be slow, as it has to call into OS functions.
Also allows for the removal of the init/quit time functions, as they are no longer needed.
This will provide a quick and easy way of clearing the error when a function succeeds, if we want to do that in a more widespread way.
For now we guarantee that SDL_Init() will never have an error set when it returns successfully.

The "jump magic" codepath was never written, and would have involved a lot
of low-level and platform/processor/compiler specific work.
A better solution is for compilers to treat the function call in the jump
table functions as a tail call, which would effectively produce the same
result in a portable way.
Clang already has a way to do this that we could add later. But this wouldn't
need a separate "jump magic" section.
This was hardcoded to disabled, since building it in bloated the binary
massively for little gain (one could probably accomplish this same thing
with ltrace or something).
If we need it, we'll pull it out of revision control.
