Frank Praznik 4f3d4bd110 wayland: Add the ability to import and wrap external surfaces 
Add the ability to import and wrap external surfaces from external toolkits such as Qt and GTK.

Wayland surfaces and windows are more intrinsically tied to the client library than other windowing systems, so it is necessary to provide a way to initialize SDL with an existing wl_display object, which needs to be set prior to video system initialization, or export the internal SDL wl_display object for use by external applications or toolkits. For this, the global property SDL_PROPERTY_GLOBAL_VIDEO_WAYLAND_WL_DISPLAY_POINTER is used.

A Wayland example was added to testnative, and a basic example of Qt 6 interoperation is provided in the Wayland readme to demonstrate the use of external windows with both SDL owning the wl_display, and an external toolkit owning it.

Simple DirectMedia Layer

https://www.libsdl.org/

Simple DirectMedia Layer is a cross-platform development library designed to provide low level access to audio, keyboard, mouse, joystick, and graphics hardware via OpenGL and Direct3D. It is used by video playback software, emulators, and popular games including Valve's award winning catalog and many Humble Bundle games.

SDL officially supports Windows, macOS, Linux, iOS, and Android. Support for other platforms may be found in the source code.

SDL is written in C, works natively with C++, and there are bindings available for several other languages, including C# and Python.

This library is distributed under the zlib license, which can be found in the file "LICENSE.txt".

The best way to learn how to use SDL is to check out the header files in the "include" subdirectory and the programs in the "test" subdirectory. The header files and test programs are well commented and always up to date.

More documentation and FAQs are available online at the wiki

If you need help with the library, or just want to discuss SDL related issues, you can join the SDL Discourse, which can be used as a web forum or a mailing list, at your preference.

If you want to report bugs or contribute patches, please submit them to our bug tracker

Enjoy!
