This makes it easier for games that don't use the gamepad API to handle D-Pad navigation, and is consistent with many other non-HIDAPI mappings.
Fixes https://github.com/libsdl-org/SDL/issues/8754
Send fullscreen enter/leave events, which will implicitly update the fullscreen flag. Manually setting the flag will suppress attempts to send the events later, as the flag is used for deduplication purposes in the event code.
Matches the one in `GetMouseMessageSource()`.
From my testing on Windows 11, the lower 8 bits in touch events cycle
trough the values 0x8c-0x95 in order.
The udev container issue is mostly to do with device notifications
and netlink. The device classification stuff just pokes file in /sys
and /run/udev. Doesn't hurt to try it first for classifying joysticks
and then fall to the guess heuristics if it fails.
The call stack is:
We want to use this instead of the desktop mode because the view may be in a different orientation than the device orientation, which the desktop mode is based on.
Don't mark fullscreen windows as having a title bar if the window is borderless, or it can end up in a weird, pseudo-decorated state when leaving fullscreen if the borders were toggled back on while the window was fullscreen.
Setting the window styling when about to leave fullscreen caused issues with this as well and is no longer needed, as it is ensured that the window's resizable state won't change while in a fullscreen space, or in a transition period.
Don't check the fullscreen flag when toggling resizable, bordered, always on top, minimum size and maximum size, as the flag doesn't reflect pending async changes that may be in progress.
These properties can be made to be safely toggled while the window is in fullscreen mode and applied when returning to windowed mode, which ensures that requested window settings aren't lost if calling these functions while async fullscreen changes are in flight.
We'll use properties for new data associated with a surface, which lets us preserve ABI compatibility with SDL2 and any surfaces created by applications and passed in to SDL functions.
Added support for getting the real controller info, as well as the function SDL_GetGamepadSteamHandle() to get the Steam Input API handle, from the virtual gamepads provided by Steam.
Also added an event SDL_EVENT_GAMEPAD_STEAM_HANDLE_UPDATED which is triggered when a controller's API handle changes, e.g. the controllers were reassigned slots in the Steam UI.
