XInput2 can send slave button presses before FocusIn events, which can confuse the click-through suppression logic. A window must have keyboard focus to grab the mouse anyway, so ignore slave presses when lacking keyboard focus.
(cherry picked from commit ef9a5b7040)
XInput2 may send mouse buttons presses on both the master and slave devices, and the click-through button event should be ignored on both if required.

This simply toggles a flag that rejects DnD offers if false. Events were previously dropped silently, but rejecting the offer makes some desktops display a proper icon when the drop will not work.

This fixes a UBSAN warning later in this function where it calculates
(1 << SDL_BITSPERPIXEL(surface->format)). The bpp might be >= 32 and
out of range for a bit shift.

Because the blend mode is explicitly set to SDL_BLENDMODE_NONE, it doesn't matter if there's a transparency channel in the texture format or not for opaque windows. This ensures that a 32-bit format is used with Metal instead of SDL_PIXELFORMAT_RGB565.

Some compositors may dispatch this too early, during the initial empty commit, when subsurfaces are attached to a toplevel window, but a buffer has yet to be committed to the parent surface. Don't set the frame callback until the initial empty commit is done, so it will be called when the actual parent surface frame is committed.
(cherry picked from commit e3393e6304)
Some compositors send the frame callback as part of the initial configuration sequence, so the window may already be past the "waiting for frame" state. Ensure that the exposure event is always sent.

Under the right conditions, this extension can result is smoother resizing when rendering with OpenGL, however, it is known to cause problems in certain cases, such as when handling presentation externally.
Gate it behind a hint, and disable it by default. Developers can selectively enable it when they verify that they meet the criteria for using it, and that it behaves correctly in their apps/games.

If the cursor was created with a temporary surface that was pointing at external memory, then when the cursor is used it might be referencing memory that had already been freed.
(cherry picked from commit f6f4664ed1)
Natural scrolling affects both axes, and the compositor may not send the vertical axis orientation if the frame has no vertical scroll motion, so purely horizontal events need to be flagged as inverted as well.
(cherry picked from commit 3ee0439ae5)
The code is using `controls.window` before checking if it isn't null.
I found this bug by accident when I tried to run `SDL_ShowSimpleMessageBox`.
It first tried using Wayland with `zenity`, but since I don't have `zenity`, it fallbacked to `X11_ShowMessageBoxImpl`.
For some reason it couldn't create a window, maybe something related to XWayland, so `controls.window` was `NULL`.

Only send the unblocking exposure event once per frame, so that clients using an event watcher won't redraw excessively.
Also ensure that the unblocking exposure is always sent on the libdecor path.

This reverts commit 0231ff03de.
This causes SDL to return 1024x768 when asking for a best fit to 640x480 (thanks @AJenbo), so I'm reverting this until we can investigate more.
(cherry picked from commit 7b23cd62ca)
When the pointer isn't being scaled, make sure the cursor scale factor is set to that of the window to avoid blurry cursors on high-DPI desktops, and use the inverse of the pointer scale value when selecting buffers for size-adjusted cursors. Fixes a regression from adjusting custom cursor sizes when using scale to display mode, and ensures that the best buffer size for the scaled cursor is always selected.

Even without the text input protocol, basic text can still be obtained from individual keys and the composition system.

All locked front buffers must be released prior to destroying
the EGL surface to avoid causing a UAF in libnvidia-egl-gbm.so.
(cherry picked from commit 463b6be133)
When a window has the pointer grabbed, the X server will grab all master device events, and XInput2 will continue to deliver slave events to the window immediately under the pointer, regardless of grab status. Only send slave pointer events to the focused window, and fall back to the core X events to catch button presses missed when the pointer is over another window.
(cherry picked from commit 0fc9db9b82)
This works inside of containers, and supports passing an activation token with the request, which is needed on Wayland to transfer focus to the browser.
