- SDL_MaximizeWindow, MinimizeWindow, SetFullScreenWindow, etc are not meant to show the window if it isn't currently visible, but on some platforms
(e.g. Windows) it isn't possible to set this state without also showing the window so cache the flags in a pending_flags field until SDL_ShowWindow is
called. Then replay the pending flags through ApplyPendingFlags (hoisted out from SDL_FinishWindowCreation).
If the text-scaling-factor setting is available via D-Bus, add a listener and update the content scale values for the displays if the value is changed during runtime.
Factors out the D-Bus message pump from the system theme detection code to the general D-Bus code, as it's now used for more purposes than just the system theme.
Expose the text scaling factor (aka the global scale factor on KDE) as the display content scale value so applications can scale themselves as necessary.
If D-Bus is unavailable or retrieving the setting fails, fall back to trying the legacy GDK_SCALE envvar before reverting to the default 1.0 value.
Change 8067023 by mikela:
Add SDL_HINT_WINDOW_ACTIVATE_WHEN_RAISED to SDL_RaiseWindow
- When set to false, this allows SDL_RaiseWindow to bring a chosen window to the top of the stack but not force input focus to it
Change 8067041 by mikela:
Rename SDL_HINT_WINDOW_NO_ACTIVATION_WHEN_SHOWN to SDL_HINT_WINDOW_ACTIVATE_WHEN_SHOWN
We have gotten feedback that abstracting the coordinate system based on the display scale is unexpected and it is difficult to adapt existing applications to the proposed API.
The new approach is to provide the coordinate systems that people expect, but provide additional information that will help applications properly handle high DPI situations.
The concepts needed for high DPI support are documented in README-highdpi.md. An example of automatically adapting the content to display scale changes can be found in SDL_test_common.c, where auto_scale_content is checked.
Also, the SDL_WINDOW_ALLOW_HIGHDPI window flag has been replaced by the SDL_HINT_VIDEO_ENABLE_HIGH_PIXEL_DENSITY hint.

sdl12-compat can get into a state where a color-keyed surface is
marked for blending, but wants to blend with full alpha (which
is the same as _not_ blending), so rather than fail to find a
blitter in that case, it just selects the colorkey blitter.

It turns out that screen coordinates were confusing people, thinking that meant pixels, when instead they are virtual coordinates; device independent units defined as pixels scaled by the display scale. We'll use the term "points" for this going forward, to reduce confusion.
Re-writes the clipboard data handling in wayland to an on demand
solution where callbacks are provided to generate/provide the clipboard
data when requested by the OS.
Wayland doesn't support getting the true global cursor position, but it can be faked well enough for what most applications use it for: querying the global cursor coordinates and transforming them to the window-relative coordinates manually.
The global position is derived by taking the cursor position relative to the toplevel window, and offsetting it by the origin of the output the window is currently considered to be on. The cursor position and button state when the cursor is outside an application window are unknown, but this gives 'correct' coordinates when the window has focus, which is good enough for most applications.
If the popup is positioned such that it requires correction on both the x and y axes, it will be aligned with parent only at the window corners, which is neither overlapping nor adjacent. In this case, nudge the window plus or minus one screen unit on the x axis so it is properly adjacent to the parent and within spec guidelines.
An in-place swizzle mutation was erroneously inside of a loop, which
caused each consecutive 4-pixel vector to alternate between correct and
incorrect endianness.
The bug was introduced in 715e070d29.
Thanks to RobbieAB for reporting the bug.

The window geometry will be updated when in underlying shell surface config handler, before the config is ack-ed, so no need to do it in the popup config handler.
Validate and reposition popups in any case where the position or size may have changed. In particular, this fixes cases where the position parameters were adjusted while the window was hidden, as the new values weren't being applied in all cases.
Popups beyond the right and bottom borders of the window must be width/height minus one in order to be considered adjacent and not be instantly closed or cause a protocol error.
In this case we want the display mode pixel to screen coordinates to be 1:1 ... but we lose information about the UI scaling of the display - is that okay?
As child windows can be recursively destroyed when their parents are destroyed, emit an event to notify the application when a window is being or has been implicitly destroyed so that it can appropriately clean up any associated resources.
If the application has registered an event watch, the destroy message will be received when the window handle is still valid, so the application can retrieve and release any userdata associated with the window. If the message is processed at any time after that, the window handle is already invalid and the ID is only useful for application-side bookkeeping purposes.
Insert new displays at the end of the list instead of the front so that the initial ordering, as exposed by the compositor, is preserved. This is particularly important when the compositor exposes the xdg-output instance after the wl_output instance, as xdg-output must be attached to the outputs in the same order that wl_output exposed them, or they can be added to the SDL output list in reverse order.
Destroy any proxy wrappers and callbacks before the associated event queues to silence libwayland warnings about destroying the queues while proxies are still attached.
wl_compositor v6 introduces the preferred buffer scale event, which serves a similar function to the fractional scale protocol, but deals in integer scale factors. Listen to this event when the wl_compositor version is >= 6 and the fractional scale protocol is not present to set the scale factor for surfaces.
- Composited windows seem to need to actually paint (or appear to paint) through calls to Begin/EndPaint to properly validate
their update region. If not done they will continue to receive WM_PAINT messages for the same region.
When X11_UpdateWindowPosition() was called and the position didn't update
we would fire an SDL_EVENT_WINDOW_MOVED event with the global x,y for
the pop-up instead of the relative position for the pop-up.
This change ensures we always have a relative position for pop-ups before sending
the SDL_EVENT_WINDOW_MOVED event.
