Add aspect-correct output of scaled video modes and a hint to control this behavior (aspect, stretch, or none).
The Wayland spec states that fullscreen surfaces that do not cover the entire output shall be centered with the borders masked by the compositor, so no additional work is required aside from calculating the proper window dimensions.
The default is still 'stretch' mode, as some window managers as of this time (KDE and older versions of GNOME still found in LTS distros) don't behave according to the spec and present an unmasked window that is not centered, so it's not yet safe to change the default.
Locally, I do make multiple build directories for various purposes, like "build-debug", "build-release", "build-novideo", etc. Also, Qt Creator (if configure it) may automatically create build directories that always starts with a "build-*" prefix.
- Fix places working with window coordinates that need to call SDL_RelativeToGlobalForWindow or SDL_GlobalToRelativeForWindow
- Remove NSScreen param from ConvertNSRect(). Reflecting the Y coordinate is done relative to the main screen height (which ConvertNSRect
was already doing) so the explicit screen isn't needed.
- Refactor NSScreen lookups for point/rect and fix getting the screen for Cocoa_SetWindowPosition() to get the screen for the new position and
not the window's current screen (which may not exist if the window is off-screen).
- Fix re-associating the popup and parent window when the child window is shown. Hiding a child window removes it from the window hierarchy
and so must be added when the window is shown again.
- Allow popup windows that are not tooltips to gain key focus.
If SDL_HINT_APP_ID is set, pass it as the application.id to pipewire.
This gives any pipewire-based tools a hint to find an associated
.desktop file for icons, etc.
Apparently when using the Xbox One Wireless Adapter, using XInput at the same time as raw input will cause the controller to turn off immediately after connecting. This appears to be a bug in the Windows 11 driver stack, but since WGI provides all the extended functionality we need, this can be turned off for now.

In case something reports "Device" when we expected "device", etc.
Reference Issue #6835.
(cherry picked from commit df9d0fb332ea65c3fc47f72574851c91da2c912b)
Consolidate the X11_WMCLASS and WAYLAND_WMCLASS envvars into one SDL_HINT_APP_ID hint. This hint serves the same purpose on both windowing systems to allow desktop compositors to identify and group windows together, as well as associate applications with their desktop settings and icons.
The common code for retrieving the value is now consolidated under core/unix/SDL_appid.c as it's common to *nix platforms, and the value is now retrieved at window creation time instead of being cached by the video driver at startup so that changes to the hint after video initialization and before window creation will be seen, as well as to accommodate cases where applications want to use different values for different windows.
XRandR supports applying transformations to an output's picture
including changes to scale. Such scaling is used by some desktop
environments under feature names such as "fractional scaling" to
accomodate HiDPI devices. Alternatively, such scaling can be enabled by
a command such as the following:
xrandr --output DP1 --scale 0.5x0.5 --filter nearest
XRandR scaling has no "HiDPI awareness" or other way for an application
to signal that it wants to work with physical display pixels, and so all
we do is scale SDL's returned display modes so that applications receive
the number of usable pixels that they expect.
By default SDL will only enumerate controllers, to reduce risk of hanging or crashing on devices with bad drivers and avoiding macOS keyboard capture permission prompts.
The hidapi method of storing the error on the device is not thread-safe, and not only could it result in a double free if multiple threads were setting the error at the same time, but SDL could be trying to use the error message and have it be freed out from under it by another thread.
Use SDL's error functions since they already use thread-local storage.
This reverts commit 2b386b6c80.
This isn't the right approach. Even if the string itself isn't double-freed, it can be returned to the application and then freed while the application is trying to use it. This really needs to be in thread-local storage to be completely safe.
In SDL we already have a global thread-local error string, so I'm going to make an SDL-specific change to handle the error strings safely.
The error string is not protected by a mutex, and can be set from multiple threads at the same time. Without this change, it can be double-freed. It can still be double-allocated, leading to a memory leak, but at least it won't crash now.
