These are integer values internally, but the API has been changed to make it easier to mix other render code with querying those values.

My phone captured 1920x1080 images even though the highest reported format was higher resolution, so I adjusted testcamera to be able to handle different sized images than expected.

This declares that any `const char *` returned from SDL is owned by SDL, and
promises to be valid _at least_ until the next time the event queue runs, or
SDL_Quit() is called, even if the thing that owns the string gets destroyed
or changed before then.
This is noted in the headers as "the SDL_GetStringRule", so this will both be
greppable to find a detailed explaination in docs/README-strings.md and
wikiheaders will automatically turn it into a link we can point at the
appropriate documentation.
Fixes#9902.
(and several FIXMEs, both known and yet-undocumented.)
This extends the display scaling mode to be global and work in terms of pixels everywhere, with the content scale value set on displays. The per-window property had some issues, and has been removed in favor of retaining only the global hint that changes all coordinates to pixel values, sets the content scale on the displays, and generally makes the Wayland backend behave similarly to Win32 or X11.
Some additional work was needed to fix cases where displays can appear to overlap, since Wayland desktops are always described in logical coordinates, and attempting to adjust the display positions so that they don't overlap can get very ugly in all but the simplest cases, as large gaps between displays can result.
The flags parameter has been removed from SDL_CreateRenderer() and SDL_RENDERER_PRESENTVSYNC has been replaced with SDL_PROP_RENDERER_CREATE_PRESENT_VSYNC_NUMBER during window creation and SDL_PROP_RENDERER_VSYNC_NUMBER after renderer creation.
SDL_SetRenderVSync() now takes additional values besides 0 and 1.
The maximum texture size has been removed from SDL_RendererInfo, replaced with SDL_PROP_RENDERER_MAX_TEXTURE_SIZE_NUMBER.
The shorthand version of this function didn't allow specifying a controller name, which seems pretty important. It seems like anyone actually implementing a virtual joystick is going to want to use some of the extended functionality.
This allows applications to re-query the values if the system locale is changed during runtime, and better matches the other locale functions. A note is included in the documentation mentioning that this can be slow, as it has to call into OS functions.
Also allows for the removal of the init/quit time functions, as they are no longer needed.
Added macros SDL_SINT64_C() and SDL_UINT64_C().
Integer suffixes of SDL_MAX_SINT64, SDL_MIN_SINT64, SDL_MAX_UINT64
and SDL_MIN_UINT64 are now system dependent.
Press 'c' to center the pointer in the window using relative coordinates via SDL_WarpMouseInWindow().
Press alt+'c' to center the pointer in the window using global coordinates via SDL_WarpMouseGlobal().
