* Implemented EnumerateStorageDirectory()
* Implemented RemoveStoragePath()
* Fixed init failure if the application previously crashed with a write batch in progress
* Allow creation of multiple Steam storage objects, the write batch is complete when the last storage is closed
* Check to see if a file exists in GetStoragePathInfo()
* 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.
In the unlikely case that the overflow check should fail,
the else clause would switch to the truncated stack message
without updating the len variable. This would contain the
return value from vsnprintf(), meaning it could point beyond
the buffer.
The subsequent code which trims NL and CR from the buffer,
would then read -- and possibly write -- out-of-bounds.
To fix this, we split the two joint conditions into separate
if-clauses, and adjust the len variable in the case where we
know the message buffer was truncated.
This prevents validation errors on D3D12 caused by the previous solution
that utilized internal D3D12 functions. This is still the fallback
solution if WinPixEventRuntime.dll is not present in PATH, but a warning
is printed to let you know how to fix these errors.
At best, this is a no-op.
At worst, it might:
- Clobber a signal handler someone registered after us
- Overwrite the signal mask or flags
- Cause unregistration to fail (sigaction() isn't guaranteed to return the exact pointer passed to signal())
If video is initialized, the main thread is the one that initialized video, otherwise if events are initialized, the main thread is the thread that initialized events, otherwise the main thread is the one that called the main function.

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.
Grabbing the mouse interrupts touch events in progress, so if someone
enables relative mode while a button is pressed, wait for the button to
be released before grabbing the mouse.
