Cap the elapsed time to something sane in case the compositor sends a bad timestamp, which can result it in it looking like the key has been pressed for a *very* long time, bringing everything to a halt while it tries to enqueue all the repeat events.
The function SDL_GetCurrentKeymap() would return null instead of the actual bound keymap for non-latin layouts if certain mapping options were set. Add a parameter to ignore the keymap options and always return the actual bound keymap, which is needed in the Wayland backend to avoid spamming keymap changed events on every keystroke with certain layouts.
The text input cursor should reflect the cursor position, not the entire text input rect. Set it correctly so that IME chooser dialogs appear in the correct location.
This can be toggled per-window, so use the individual window flags instead of the global toggle to selectively enable it only for the relevant window in a multi-seat scenario, as is already done with keyboard and pointer grabs.
This and its related commits introduced some bugs and quirks such as duplicated and delayed/missed key events that can't be easily worked around, so revert this for now.
This reverts commit 47162a4168.
Compositors typically send keyboard, pointer, touch, and tablet leave events when a window is destroyed, however, this is not guaranteed behavior, and at least one compositor in widespread use doesn't always send pointer leave events immediately upon destroying a window. Ensure that all references held by seats to a focused window are removed before the underlying window surface and structs are destroyed to prevent potential segfaults if the seats are immediately destroyed after the window.
The surrounding code in all of these instances expects the Unicode
variants. Previously, this code mixed Unicode and ANSI/ASCII calls if
`UNICODE` was undefined, which caused type and logic errors. Explicitly
spelling out the W removes any reliance on that macro.
IME text events can result in sending duplicate key press events, which will result in undesired repeated key presses. Since the events are exact duplicates, compare the serials to filter out redundant key down events.
The Module interface is the one used by the outside world. This code
is inside the module itself so can use the internal name, avoiding the
need to export this function on the Module at all.

The xserver will still send EnterNotify events while the pointer is captured, and the grab shouldn't be updated in these cases, as it will cause the capture to be lost.
If it is known that the window will immediately enter fullscreen upon being shown, set the borderless style when showing the window to hide the borders, or they may linger in the background if the client takes some time to draw the first frame.
Unnecessarily calling ShowWindow with SW_RESTORE when applying the window flags must be suppressed in this case, or the borders can reappear in a weird, partial state.
sdl2-compat will call SDL_GetDisplayForWindow() when querying the display to use for fullscreen, which won't always be correct if the backend can't actually reposition the window. When calling this function, get the ideal fullscreen display and store it in a property for retrieval by sdl2-compat.
Mouse button events that trigger a hit test are not passed to the client, but the client may still query the global mouse button state from within the hit test handler, so the reported buttons need to be accurate. Query the buttons directly from the seat instead of the higher global mouse state to match the behavior of other platforms.
The low 16-bits of the message extra info is an event sequence number when using the Wacom tablet with Windows Ink disabled. The high bits of normal mouse motion when using touch input match the touch signature, 0xFF515700. The high bits of raw input mouse motion when using touch input do not match that signature, so we have to check for the touch bit in that case.

The problems are two-fold. When this happens a WM_POINTERDOWN event is sent with IS_POINTER_INCONTACT_WPARAM() evaluating as true. So when SDL_SendPenButton() is sent for the barrel button, there is no pen in contact yet, so the right mouse button is sent. Then SDL_SendPenTouch() is sent, which generates a left button press event.
Fixes https://github.com/libsdl-org/SDL/issues/12926
These events fire for other things, such as pressing a barrel button while
the pen is hovering.
The correct thing to do is check IS_POINTER_INCONTACT_WPARAM in the event.
If the pen is already touching or not, SDL_SendPenTouch() will do the right
thing, so it's safe to call it even if we're already in the right state.
By default, popups are automatically constrained to be completely within display bounds, so as not to cut off information and result in an unusable menu, or unreadable tooltip. In some cases, however, this is not wanted, so a property to toggle this behavior is added.
There are also cases where the client may not want a popup menu to implicitly grab the keyboard focus, as is the default behavior, so popup menus now respect the focusable flag/property, as well as being able to toggle focus grabbing via SDL_SetWindowFocusable().
When showing or hiding a popup menu, manually check and set the focus if the new topmost window under the cursor is an SDL window. Otherwise, the focus won't be updated until the cursor is actually moved.
There is a quirk with XInput2 mouse capture that causes a leave event to be sent if the pointer moves out->in->out, which breaks mouse tracking outside the window. If the mouse leaves the window with buttons pressed, continue tracking it until the buttons are released.
- IsIconic/IsZoomed must be checked after sending SDL_EVENT_WINDOW_SHOWN as that may trigger window operations if any are pending from when
the window was hidden. e.g. the window may be shown, which triggers SDL_MaximizeWindow and a new WM_WINDOWPOSCHANGED where
SDL_EVENT_WINDOW_MAXIMIZED is sent, then control returns to the original WM_WINDOWPOSCHANGED which would not think the window is zoomed
and send SDL_EVENT_WINDOW_RESTORED.
According to the documentation and testing the `emscripten_webgl_create_context` function returns `0` on error as oppposed to a negative number. This was causing the error message to be empty when the later `emscripten_webgl_make_context_current` call fails given the invalid context.
