Calling SteamAPI_InitEx() will set environment variables that SDL uses to properly support the Steam virtual gamepad. Make sure that we fall back to the real environment for the variables that Steam sets.
We only want to change cursor display scale if the application or the user opts in by setting a hint. Otherwise cursors could change size unexpectedly when upgrading to SDL 3.4.0.
If you want access to the SDL_REVISION define,
you must explicitly include this header.
Language like this was present in the SDL2 version,
but disappeared in SDL3, even though it's still true.
This reverts commit a3992f504c.
The reason SDL_revision.h was not included by SDL.h or SDL_version.h is because SDL_revision.h changes with every git commit, causing a complete SDL rebuild for every trivial git commit.
* GPU: D3D12: Missing WinPixEventRuntime.dll now logs warning at device creation time.
* GPU: D3D12: Debug label functions are now a no-op when WinPixEventRuntime.dll is missing.
* Docs: GPU: Debug function documentation now notes WinPixEventRuntime.dll is required under D3D12.
We already set the main thread when creating a thread or calling SDL_Init(), and applications can call SDL_SetMainReady() themselves for special cases, so there isn't a lot of value of forcing everyone through the SDL_RunApp() flow.
Fixes https://github.com/libsdl-org/SDL/issues/14580
This lets applications choose which scene their windows are being created in. For example one window might be video output in a scene with a session role of UIWindowSceneSessionRoleExternalDisplayNonInteractive, and video controls in a scene with a session role of UIWindowSceneSessionRoleApplication.
It'll usually replace it with `{ "SDL_app", NULL }`, but things like Win32
can query the OS for the original command line arguments.
This allows apps/scripting languages that provide their own entry points to
use SDL_RunApp and not have to worry about how to compose an argv array on
things like Windows, when SDL was going to do it for them anyhow.
Most things won't experience any change with this commit, including apps that
that want extra control but originate in a standard main()-style entry point
and can just pass the existing argc/argv through to SDL_RunApp.
Windows isn't addressed here, since a previous commit already updated it.
GDK has a different fix here, but we'll unify that in a later commit.
Closes#12676.
